What are at-home tray-based teeth whitening systems? While several systems for teeth whitening (teeth bleaching) exist, in the last decade tray-based whitening has become the most popular type of at-home bleaching products. This technique utilizes a plastic tray that has been fabricated so to fit comfortably over a person's teeth. The person places bleaching gel (carbamide peroxide) into the tray and the tray is then worn for multiple hours a day for some weeks, as the effects of the whitening process take place. At home tray teeth whitening is a safe and effective way for most people to bleach their teeth but anyone using this type of teeth whitening system needs to realize that the majority of their whitening activities will not be directly supervised by a dental professional. Because of this, anyone bleaching their teeth must be certain that the specific whitener they are using is safe, and that they know how to use this product in an appropriate manner. What influences the shade of teeth? When will at-home tray-based teeth whitening work?At any specific point in life, the coloration of a our teeth can be influenced by several factors. Before you initiate the use of any at-home tray teeth whitening (teeth bleaching) system it is important for your dentist to determine the possible causes of your tooth discoloration. Having an idea of what has caused your discoloration will help your dentist estimate how much lightening the teeth whitening process can be expected to achieve. - Baseline tooth color. The teeth of humans, as a race, display a wide range of shades of white. There is no one specific color that a person's teeth are supposed to be. Some person's teeth are just naturally lighter in color than others. - Chromogenic agents. Beyond a person's baseline tooth shade, it seems to be a fact of life that as years pass our teeth tend to absorb discoloration and stain. The degree to which a person's teeth will darken can often be related to the amount of repeated exposure they have had to "chromogenic agents". Tea, coffee, soft drinks and red wine are each known to have a darkening effect on teeth. Smoking is also recognized as an activity that stains teeth. - Exposure to certain medicines. Some people have tooth staining because they had a systemic exposure to certain medicines. One known culprit is the antibiotic tetracycline. When children are given tetracycline during those years during when tooth enamel is forming, their teeth can acquire a yellow-brown to blue-grey staining. For this reason tetracycline related antibiotics are seldom prescribed for children 8 years and younger or for pregnant women. The use of the minocycline even by adults has been reported to cause grey tooth staining. Ingestion of excessive amounts of fluoride by children during their period of tooth development can cause a type of tooth staining termed "fluorosis". In its most common form fluorosis appears as chalky-white areas on a tooth. In more severe forms fluorosis can cause brown tooth staining and even result in tooth surface pitting. (Parents should be aware that a common source of fluoride ingestion can be when children swallow toothpaste. It has been suggested that children under the age of 5 swallow essentially all of the toothpaste placed on their brush.) - Individually darkened teeth.There are times when a single tooth has become darker than its neighboring teeth. As an example, it is very common that a tooth that has had root canal treatment will darken as years pass. Teeth that have a history of having been traumatized, such as being bumped in an accident, will often darken with time too. (This darkening may or may not indicate significant problems related to the health of the nerve in the tooth. Any individually darkened tooth should always be evaluated by a dentist.) Does tray teeth whitening always work? While your dentist cannot know beforehand the precise level of whitening results you will achieve or how long it will take, they should be able to give you a general idea of what changes might be possible based on their experiences with other patients. Tray teeth whitening systems using a 10-16% carbamide peroxide whitener can usually be expected to make at least some improvement in shade for teeth found in all of the categories discussed above, however certain types of tooth darkness will be more resistant to whitening than others. Additionally, the results a person is able to obtain, and the time it takes to achieve them, will depend on their degree of compliance with their dentist's instructions. Those people who feel that they were pleased with the shade of their teeth when they were younger but now, at an older age, have found that their teeth have yellowed somewhat will most likely find the results of a tray teeth whitening system very satisfactory. This type of staining, which is often due to exposure to chromogenic agents such as tea and coffee, is commonly resolved by two to six weeks of bleaching. Fairly dark tooth staining which has been caused primarily by a person's smoking might take upwards of three months of treatment to successfully whiten. More difficult cases to bleach will be those instances where a person does not so much feel that their teeth have stained with time but instead were always too dark, even when they were younger. While tray teeth bleaching can be expected to make a shade improvement in these cases, the degree of whitening will be less predictable. Teeth falling into this bleaching category will be those with an inherently dark baseline color and those with tetracycline or brown fluorosis staining. When won't the tray teeth bleaching systems work? The tray-based at-home teeth whitening (teeth bleaching) process is not always predictable. Most definitely some tooth discolorations will be more resistant to bleaching than others. Your dentist, as part of their initial examination, will need to ascertain the most likely cause of your tooth staining. Having done so they will then be able to convey to you what type of whitening results might be expected. - Unnatural tooth shades. Your dentist will not be able to unconditionally guarantee that you will be pleased with the outcome of your at-home teeth whitening efforts. This is because many people have a very unrealistic idea of what constitutes a natural shade for teeth. Some people compare their teeth to the teeth of those persons they see featured in films, TV, and magazine advertisements. You should be aware of the fact that the shades of many models' and actors' teeth fall into the realm of "unnatural". Often these extreme shades of white have been achieved by means other than by bleaching (such as by placement of crowns, or porcelain veneers), or this extreme whiteness never existed at all but instead was created by touching up a picture. At-home tray-based teeth whitening cannot be expected to lighten existing dental work. The at home teeth bleaching processes cannot be expected to make a color change in the dental work you have already had placed (porcelain veneers may be affected). Before the bleaching process is begun a person should have discussed with their dentist how much post-bleaching dental work will be needed. - At-home tray-based teeth whitening can possibly lighten teeth with porcelain veneers. There is an exception to the rule that existing dental work will not lighten and this exception involves teeth with porcelain veneers. Veneers are translucent shells of porcelain that have been bonded onto the front side of a person's teeth. While the tooth bleaching agent will not change the color of the veneer itself it will be able to permeate the tooth from the backside, thus lightening the tooth structure which lies under the veneer. Because veneers are translucent, the net effect can be that the tooth, from the front side, appears whiter. - Teeth with gum recession. Some people have gum recession on one or more teeth. Usually the root surface that becomes visible as gums recede has an appearance that is somewhat darker than the rest of the tooth. This is because root surfaces are not covered by enamel but are instead composed of another naturally darker material called dentin. Tray teeth whitening systems won't effectively lighten dentin. This means that the color of the root portion of the tooth (which shows where the gum recession has occurred) will not change noticeably as a result of your bleaching efforts. What steps are involved with tray teeth whitening systems? 1. Step: The pre-bleaching dental examination. Your dentist will need to perform a thorough dental examination prior to the initiation of the teeth whitening process, so he will know that you are in good general dental health. As a part of this examination your dentist will document the current shade of your teeth, sometimes by taking photographs, and also discuss with you the history related to your current tooth shade. This discussion will help your dentist both identify the nature of the discoloration of your teeth and determine if tray teeth whitening is an appropriate method by which to make a change. Once having determined the most likely cause of your tooth discoloration your dentist will be able to provide you with an idea of what type of improvement can be expected and how long the bleaching process might take. During the examination you and your dentist must discuss and decide if you will whiten both your upper and lower teeth, or just one or the other. Usually a person's greatest concern is the appearance of their front upper teeth, and some people start out by just bleaching them. During the examination process your dentist will identify any dental work which exists on those teeth you have chosen to whiten. It is imperative for you to realize that the shade of existing dental restorations will not lighten. Restorations on whitened teeth will need to be replaced after the bleaching process has been completed. 2nd Step: Taking impressions for the bleaching trays. An important feature of dentist dispensed tray-based teeth whitening systems that can both increases the technique's effectiveness and minimizes its side effects is the use of custom fitted bleaching trays. The first step in creating these trays is for your dentist to take impressions of your teeth. From these impressions your dentist will create plaster casts (molds). Your bleaching trays in turn will be crafted on them. Usually, once impressions have been taken, your dentist will need at least a few days to complete the tray fabrication process. 3rd Step: Fitting the custom bleaching trays. Your dentist will ask you to make an appointment so they can evaluate, and refine as necessary, the fit of your bleaching trays. The bleaching trays themselves are usually clear, they are often made from a soft flexible plastic, and one is made for your upper teeth and a separate one is made for your lower teeth. Usually bleaching trays have been trimmed so they fully cover each tooth but come just short of lying on your gums. 4th Step: Instructions about how to place teeth whitener in the trays. During the dental appointment when your bleaching trays are fitted your dentist will also dispense to you an initial quantity of teeth whitener (10%-16% carbamide peroxide). Usually this is a gel that is contained in a small syringe or plastic bottle. Your dentist will show you how and where to place the whitener in your bleaching trays. As a means of minimizing the amount of whitening gel used during each application, the whitener is usually just placed on those aspects of the tray which touch the front side of your teeth and only in those portions of the tray which cover the teeth you want to lighten. After the whitener has been placed into the tray and the tray has been positioned over your teeth, there will usually be some excess gel that escapes from the tray up and onto your gums. As a way of minimizing any gum irritation the whitener may cause, it is best to wipe this excess away with your finger or your toothbrush. 5th Step: How long should bleaching trays be worn each day? Your dentist will provide you with specific recommendations regarding the amount of time your bleaching trays should be worn each day. If your dentist gives you a range of times, in general the more hours you wear your bleaching trays the more rapidly you will notice results. The whitening process is simply one of cause and effect. One option usually given to patients is to wear their bleaching trays at night while they are sleeping. The advantages of this method are that both the total amount of whitener and the total number of individual bleaching episodes that are needed for treatment will be minimized. This is because each application of the whitener will be in the tray long enough to produce its maximum effect. This method can be especially beneficial in those cases where the tooth staining being treated is expected to be stubborn. Another common manner in which dentist's instruct their patients to use their bleaching trays is to wear them during the day, however some may find that doing so conflicts with their normal daytime activities. While both whitening gels and bleaching trays are usually clear, they can still be visualized somewhat by others. Speech can also be affected by bleaching trays, although because they are usually thin it is usually only minimally. Daytime bleaching for less than 2 hours a day tends to waste teeth whitener and will extend the total number of days needed for treatment. Most whitening gels are effective for up to 4 hours or longer. 6th Step: Follow up appointments with your dentist. Your dentist will ask you to make periodic follow up visits to their office so they can evaluate the shade change your bleaching efforts have achieved. Tray teeth whitening is usually continued until you and your dentist have become satisfied with the color change which has taken placed or until that point at which no more whitening seems to occur. After evaluating your progress your dentist will, if they feel that more whitening is possible, dispense additional whitening gel to you. Additionally, at each follow up visit your dentist will ask you if you have experienced any side effects from the bleaching process. If you have they will make recommendations so to help you manage them. This does not mean that if you are experiencing side effects you should wait until your next follow up appointment to bring them to your dentist's attention. You should always feel free to contact your dentist regarding any problems or difficulties you have encountered. 7th Step: Terminating the at home teeth bleaching process. Once your bleaching efforts have achieved a pleasing tooth shade, or at that point in time when no more whitening appears to occur, your dentist will recommend to you to terminate the bleaching process. Once you have stopped there can be a period, possibly two weeks or so, where the shade of your teeth will relapse slightly before stabilizing. Once the shade of your teeth has stabilized you and your dentist can make plans to begin the process of replacing your existing dental work so to match the new shade of your teeth. How long do the effects of tray teeth whitening last? The effects of at-home tray-based teeth whitening can, on occasion, last fairly indefinitely but in most cases a "satisfactory" shade change is found to last for about 1 to 3 years. One study found that 42% of the persons who had under gone the bleaching process were still satisfied with the shade of their teeth 7 years later. Possibly more importantly, no one in this study, including even those who were not happy with their current tooth shade, felt that their teeth had regressed all the way back to their original pre-bleaching color. Of course once initially whitened it is an easy matter to retreat or "touch up" your teeth with additional bleaching at that point in time when it is needed. Usually this touch up bleaching is of much shorter duration than the original whitening process. Are teeth whiteners (10% carbamide peroxide) used with tray-based teeth whitening products safe? What side effects can be expected when using 10% carbamide peroxide teeth whiteners? Side effects can and do occur when using a 10% carbamide peroxide whitener in conjunction with an at-home tray-based teeth whitening system. The two most common side effects are the creation (or increase) of tooth thermal sensitivity (hot and cold sensitivity in a person's teeth), and irritation of a person's gums. Other, less frequently encountered, side effects that have been reported by patients are: sore throat, tooth pain, tingling of the tissues, and headaches. While the side effects a person encounters can be significant enough that the bleaching process must be discontinued, they are usually found to be minor. One study asked participants to rate the discomfort associated with their side effects on a scale from 0 to 10, 10 being the most painful. Most respondents rated their side effects as a 1 or 2. In all cases, if you do notice any side effects during the bleaching process, you should report them to your dentist. When just minor side effects have presented themselves a dentist will often recommend that the person just reduce the total number of hours their bleaching trays are worn each day, or recommend that the bleaching process only be performed on alternating days. Because both of these methods reduce a person's exposure to the carbamide peroxide teeth whitener, the side effects they have noticed will usually subside. In more severe cases a dentist may feel that palliative treatments, usually quite simple in nature, are indicated or else that the teeth whitening process should be stopped altogether. 1. Tooth thermal sensitivity (sensitivity to hot and cold). The teeth of people performing at-home teeth bleaching treatments can develop a sensitivity to hot and cold temperature variations. Easily half of all patients who bleach their teeth do notice at least some transient thermal sensitivity. While there is no way to predict specifically who will develop this problem there are some general indicators. Those persons who prior to bleaching already notice sensitivity to hot and cold, and also those persons who have found that they experience increased thermal sensitivity after getting their teeth cleaned are both more likely to complain about tooth thermal sensitivity while bleaching their teeth than others. Any problems with thermal sensitivity should be reported to your dentist. Usually a dentist can help you control the degree to which you do experience thermal sensitivity by either making suggestions about reducing the amount of time that you wear your bleaching trays or else by recommending some simple palliative measures such as fluoride or potassium nitrate treatments. Both fluoride and potassium nitrate are both common ingredients found in those over-the-counter toothpastes formulated to help desensitize "sensitive teeth". 2. Gingival ("gum") irritation. During the teeth whitening process a person's gums can become irritated from their contact with the teeth whitener. It is generally thought that the potential of developing gum irriation is related to the concentration of the peroxide found in the whitening gel. This is one reason why the use of a 10% carbamide peroxide whitener is typically considered to be more prudent than the use of a more concentrated one. To minimize or remedy the problem of gum irritation a dentist will usually trim a person's bleaching trays in a scalloped fashion so they cover a maximum of each tooth being bleached, but rest just short of touching the gums. Additionally as a general rule, so to help reduce gum irritation, when bleaching trays are initially inserted a person should wipe away the excess whitening gel that escapes from the tray onto their gums with their finger or a toothbrush. Will 10% carbamide peroxide teeth whiteners damage tooth enamel? Studies involving 10% carbamide peroxide whiteners have found minimal or no effect on the microhardness or mineral content of tooth enamel surfaces. Scanning electron microscope studies of the enamel of teeth that have been bleached have typically not shown any damage either. In relative terms, studies have shown that exposure to soft drinks and fruit juices cause comparable or greater alteration of tooth enamel than tooth whiteners. Will peroxide-based teeth whiteners damage my existing dental restorations? Teeth can be whitened with the at home bleaching method utilizing a 10% carbamide peroxide whitener with little concern about significant damage to a person's existing fillings. Over ten years of clinical use of these products has not revealed any obvious problems or concerns. Some studies have suggested that some degree of interaction or change might occur with white dental fillings, amalgam dental fillings, and some types of dental cements. However the clinical significance of these effects is still considered to be inconclusive. The main difficulty encountered with existing dental work is that it does not lighten during the at home teeth whitening process (the color of porcelain veneers may be affected). This means that pre-existing dental work will usually have to be replaced so to match a person's new, post bleaching, tooth shade. Will 10-16%carbamide peroxide teeth whiteners damage the nerve in my tooth? Studies conducted since the introduction of the at home teeth bleaching method in 1989 have not identified a problem related the process having a harmful effect on the health of a tooth's nerve. One study's results found that no one in their 4.5 and 7 year follow up groups reported needing root canal treatment on any whitened tooth. Should you use an over-the-counter teeth whitener? Some people will be tempted to purchase the materials for at-home whitening on their own, over-the-counter. Please realize that the key to the safety success of at-home tray teeth whitening products is three fold:
