Teeth whitening is generally safe, especially when it's done correctly and under your dentist's supervision.  

With so many teeth bleaching products available at the corner shop, you might wonder if professional whitening is really worth it, but here's what you should know. 

Professional Teeth Whitening in Charlestown

At Charlestown Dental Care, we offer professional, customised take-home teeth-whitening trays that you can use at your leisure. Custom trays take the guesswork out of teeth whitening so you can achieve your goals.

Our team takes impressions of your teeth that we use to create your trays. Custom trays fit snugly and help to keep the bleach on your teeth and away from your gums and soft tissues. Our dentists will recommend the right strength of bleaching gel for your smile, based on your sensitivity levels. You'll wear your trays for around thirty minutes per day, whenever it's most convenient for your schedule. 

Most of our patients reached their desired results in about 10-14 days. Best of all, you'll always have your trays at home to whiten your smile in the future for upcoming events like weddings or vacations. 

When Does Teeth Whitening Cause Concerns?

The biggest side effect of teeth whitening is tooth sensitivity. If you over-whiten your teeth, it can weaken enamel and cause tooth sensitivity. To help avoid this concern, our dentists will oversee your teeth whitening and recommend the right strength bleaching gel for your needs. 

Bleaching agents can also cause gum irritation if they come into contact with the gums. Generic whitening products from the store may be ill-fitting and allow bleaching gel to escape. Custom bleaching trays help protect gums and soft tissues from whitening gel.
