Achieve a
Brighter Smile
Your teeth can become darkened or stained from a number of different factors, but treatment and prevention are ways to keep your smiling shining bright and white!
Whether you’re looking to freshen up your smile for a big event or you want to confidently show off your smile, our team is here to help. Visit us for a teeth whitening appointment.

What to Expect from a
Teeth Whitening Treatment

An in-office teeth whitening treatment will start with applying a whitening gel to the surface of your teeth. To activate the gel, an LED light will be applied for a specific amount of time, depending on your teeth and desired results.
All teeth are different and can respond differently to whitening treatments. Fillings, crowns, and veneers can’t be whitened during this process, but they can be replaced to match the new shade of your teeth.
What Causes
Discoloration?
Stains and discoloration can be categorized into 3 different types: extrinsic, intrinsic, and age-related.
Extrinsic discolouration encompasses stains that affect only the surface of the tooth or the tooth enamel. This typically comes from:
- Food such as red sauces or chocolate
- Beverages such as coffee, red wine, and tea
- Tobacco in the form of cigarettes or chewing tobacco
Intrinsic stains are caused from within the tooth and look more gray in color. These stains can come from:
- Certain medications
- An injury to the tooth
- Tooth decay
- Excessive amounts of fluoride
- Genetics
Aging can cause your enamel to begin to wear down, allowing staining or yellowing to occur. Age-related discoloration can also come from a combination of extrinsic and intrinsic factors.

Maintaining Your Results
After a teeth-whitening treatment, your teeth are still prone to becoming stained or discolored. By practicing good oral hygiene, you can help maintain your results.
We can’t wait to see you smile bright! Visit us today.

Testimonials
Dr. Beck is FANTASTIC! I had jaw pain for years and always thought it was more neck and just slight TMJ. She was recommended to me by another doctor and I knew she would help the first time I went in. Finally someone who asked all the right questions and knew and understood exactly what I was feeling. I’m not done yet but I feel so much better. Dr. Beck has great bedside manner and the staff is nice as well!
Rachel Nunez
The place is sparkling clean and very modern. The receptionists are all highly professional, cheerful and friendly. Dr Beck is AMAZING! She’ll explain anything and everything to you patiently and she really knows her stuff! She has a warm and inviting affect and makes you feel like you’re in the best of hands.
Andromache Agramonte
Dr Beck’s compassion and expertise literally saved my life. I had blinding headaches felt lightheaded most of the day and focusing and making decisions were nearly impossible. Dr Beck’s listening skills and non-judgemental approach as she examined me was the start of my healing. What I discovered was with exercise and wearing a mouthguard and the loving care from Dr Beck the headaches went away. I am forever grateful to Dr Beck.
