Dealing with brown stains on teeth or discoloration that won't budge with store-bought products? Professional teeth whitening treatment can address deep or long-standing stains more effectively than over-the-counter options. 

 At the office of Dr. Troy Gombert, patients receive personalized whitening solutions that deliver noticeable results. If you're looking for one of the best teeth whitening products or want to explore custom whitening trays, call today for a consultation with our cosmetic dentist in Chandler, AZ. 

What causes deep or long-standing stains? 

Deep or long-standing stains develop over time from foods and drinks, like coffee, tea, red wine, and dark berries. Tobacco use is another major contributor to discoloration. And as we age, the outer layer of enamel thins, allowing the naturally yellow dentin underneath to show through. 

Some stains are surface-level and can be removed with regular brushing or professional cleaning. However, deeper stains that have built up over the years penetrate the enamel and require a stronger teeth whitening solution to break them down. 

How professional teeth whitening removes stains 

Professional teeth whitening involves prescription-strength agents that break down stains beneath the enamel. They penetrate the tooth and oxidize the discolored molecules, making teeth appear whiter and brighter. 

Our teeth whitening dentist in Chandler, AZ helps patients receive custom whitening trays designed specifically for their teeth. These trays hold the gel against the tooth while keeping it away from the gums, ensuring even coverage and reducing sensitivity. 

The prescription-strength gel used by a cosmetic dentist is far more effective than over-the-counter products, which often contain lower concentrations of bleaching agents and don't fit well. 

What happens at a whitening consultation 

When you visit Dr. Gombert for professional teeth whitening treatment, the process begins with an examination. We will check for any issues, such as cavities or decay, that need to be treated before whitening. Once your teeth are cleared for treatment, impressions are taken to make custom whitening trays that fit your mouth. 

When your kit is ready, you'll receive detailed instructions on how to use it, including how long and how often to apply the whitening gel. Following these instructions closely is key to achieving the best teeth whitening results possible. 

The treatment is done at home, giving you the convenience of whitening on your schedule. Most patients wear the trays for a set amount of time each day, and results begin to appear within a few days to a week. 

Teeth whitening results and timeline 

Professional teeth whitening treatment can significantly lighten deep, long-standing stains or brown stains on teeth, though the degree of improvement depends on the type and severity of discoloration. Surface stains from coffee, tea, or tobacco respond especially well, while intrinsic stains from medications may require more sessions or alternative treatments. 

Most patients see noticeable results within 1 – 2 weeks of consistent use. For optimal results, some may continue treatment for a few weeks or combine it with an in-office cleaning for an initial boost. 

Results can last for several months to a few years, depending on habits at home. Avoiding staining foods and drinks and practicing good oral hygiene as recommended by Dr. Gombert can help maintain your brighter smile long-term.

I’ve been going to Dr Gombert for years and have never had a complaint! Most visits are standard cleanings and the hygienists are experienced and professional, always do a good job. When I chipped a front tooth a couple years ago Dr Gombert went over multiple options to fix it and I decided to go all out & get veneers - now my teeth look great and feel great too!
