What is the Best Professional Teeth Whitening?

For a long time my teeth have bothered me. Too yellowed and stained to even smile much.  Before i just pick up some random teeth whitener, can you tell me what options there are and the best ones to whiten my teeth?

Best professional teeth whitening?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The BEST whitening is one that has been thoughtfully matched to your discoloration, the current comfort of your teeth now, and your personality style. 

For many people, the best result is from Deep Bleaching or Deep Whitening. It is a combination method of some whitening in the office and a short period of whitening at home. 

A significant percentage of people can get great results at home using professionally made home whitening trays. As a cosmetic dentist in Denver for over twenty years, not all the trays are the same. The other major consideration with home whitening depends a lot upon YOUR personality. To get really nice results at home, means using your trays for a concentrated number of days consistently. I have found that not everyone has the temperament to do this consistently. If that's you, don't waste your time and money as you will likely only get fair results at best.

There are many whitening agents available, but buyer beware!  Because these products are considered a cosmetic and not subject to FDA testing, there are products that will damage the tooth structure.  Buying products over the counter or even from your dentist does not guarantee it is safe.  That being said, there are safe products that will whiten and not damage the teeth.  The basic formula for successful whitening is time in contact with teeth and concentration of the whitening agent.  Using heat and light to "activate" gel increases trauma to the pulp of the tooth and has not been shown to improve whitening over gel alone. The easiest on the tooth is a low concentration of carbamide peroxide over a long time.  This can be done safely using a tray system of whitening.

When comparing different whitening systems, you need to...

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

When comparing different whitening systems, you need to take into consideration several key points:

  1. What kind of light source does this system use?
  2. Does the system contain a light filtration system?
  3. What is the strength of the whitening gel used?
  4. What is the quality of the whitening gel?
  1. There are several different kinds of light sources available and some are significantly stronger than others. Essentially the stronger the light source, the faster and more effective whitening treatment. The strongest light technology options available right now are halogen and mercury metal halide light. Beyond WhiteSpa uses a halogen light source. Other cheaper, less effective options include LED or even gimmicky, flashing lights. You want to consider a system that has one of the more powerful light source options as these will produce better, longer-lasting whitening results because the light-accelerated whitening will be stronger and deeper.
  2. For the systems with stronger light sources, you will want to use one that filters the harmful spectrums of the light out before it is exposed to your mouth. Beyond WhiteSpa has an advanced light filtration system that removes all harmful ultraviolet light and restricts the light spectrum to the most effective whitening wavelengths, between 480-520 nanometers. Other systems, including Zoom, don’t filter their light, so your mouth is being exposed to all wavelengths of light, including potentially harmful ultraviolet light. These systems require that all pink tissue in the mouth be completely blocked-out in order to avoid exposure to UV in your mouth during the treatment.
  3. Beyond WhiteSpa uses a 6% hydrogen peroxide, over-the-counter strength whitening gel; in-office dental systems use between 15%-35% hydrogen peroxide. The higher the hydrogen peroxide percentage is, the faster the treatment – but the greater the risk of sensitivity. Regardless of the strength of the gel, you will see the same results in the end. The benefit to Beyond WhiteSpa’s gentle whitening gel is that it is ideal for those clients with sensitive teeth or who are looking for a less invasive whitening treatment.
  4. High-quality whitening gels use a dual-barrel dispensing system because they contain both active ingredients and activating catalysts that actively work to accelerate the whitening process and provide the best and longest-lasting results. Cheaper whitening gels are beginning to flood the market and the results seen from these are not comparable to those from high-quality whitening systems.

Essentially, when researching what teeth whitening system you want to use to whiten your teeth, you want to ask as many questions as possible so that you can make an informed decision. The person you talk to (either aesthetician or dentist) should be able to answer your questions thoroughly and to your satisfaction. Cheaper whitening systems are starting to enter the market and you need to proceed with caution when considering using these systems. Lack of a light filtration system or a lower-quality whitening gel could seriously injure you or your client or result in bad whitening results. It is important that you feel comfortable with the quality of the system before beginning any whitening treatment and that you are familiar with how the system works and the precautions (if any) that need to be taken.

Red light to whiten teeth

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Generally, all teeth whitening options are about the same. Personally, I use a red light to whiten teeth, which gives off NO heat, reduces sensitivity, does not burn the gentle soft tissue, and is overall a safer treatment option. I also recommend that clients who are deciding on getting their teeth professionally whitened look for an office that is skilled in this practice, have had a lot of success whitening the teeth of even the toughest of cases, and also, they should look for an office that is friendly and makes them feel welcome!

The only difference in the hundreds of...

The only difference in the hundreds of dentist-prescribed whitening systems out there is the concentration of the gel (oxygenating agent) and the way it is applied to your teeth.

There are two main ways of carrying out tooth whitening:

  1. Tray based whitening. The gel is placed in a custom made night-guard which is worn for a set period for 10-14 days. The period you wear the trays depends on the type and concentration of peroxide gel.
  2. In-surgery whitening, also known as laser or power bleaching. Here, more concentrated gels are applied directly to the teeth and accelerated with heat or light (laser/power). We still make custom-made trays for the patient to use afterwards to maximise the whitening and for maintenance.

Sensitivity to laser/power bleaching is usually only for the rest of that day. We suggest avoiding very hot or cold foods. Take whatever medication you would take for a headache and if you have custom-made trays place some sensitive toothpaste in the trays and wear for 10 minutes.

Your dentist has the ability to prove two different types of whitening solutions:

The first is done with thin plastic trays that are custom fit to the patient’s teeth. The plastic trays are filled with the bleaching solution and the patient will wear these for 1 to 8 hours once or twice a day for one to two weeks.

The second option is where the teeth are bleached in the office. The bleaching process takes about an hour. Typically it is one visit, although some offices will recommend two visits. This option is commonly associated with the use of a light source to “activate” the bleaching solution.

  • Be aware that the research on the light source is divided as to whether or not it is effective. Your dentists may choose not to use the light source. He/she is not doing anything wrong. They just subscribe to a different philosophy.

The best option is always to get it assessed by the dental professional for exact cause of discolouration and best solution. Home whitening has traditionally proved to be the best of all.

Best Professional Teeth Whitening System?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Your dentist has numerous choices in bleaching systems to offer his patients.  Nowadays you can expect any of the professional bleaching systems that your dentist recommends and dispenses to work.  They seem to all whiten teeth to one degree or another.  However, dental bleaching does not whiten everyone's teeth the same.  Just like certain people's skin tans better than others, it is the same with teeth whitening.  Some will get an incredible teeth whitening result very fast, and others may undergo numerous bleaching sessions and only get a minimal result.

The good news for you is yellow teeth tend to bleach better than gray or brown teeth.

Regarding a particular brand, Discus, Phillips, Ultradent have been around a long time and over the years have captured much favor among dentists.   Some have a carbamide peroxide base and others a hydrogen peroxide base.  But bottom line, they all work, but as previously stated, it depends more upon the makeup of your particular teeth than the type of bleaching agent used.  Your dentist can evaluate your teeth and prescribe what he/she thinks will work best in your care.

In office whitening is best for yellow & stained teeth

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

If your teeth are significantly stained and yellow, in-office whitening supervised by your dentist is your best bet. I find the AcquaBrite whitening system to be the most effective, even for stubbornly stained teeth (like tetracycline-stained grey/brown teeth), with little to no sensitivity.  Using a combination of in-office whitening gel along with at home bleaching, we've gotten awesome results with our patients.
