What is Professional Teeth Whitening?

Teeth whitening is one of the quickest, most effective ways to transform your smile—and your confidence.

At St Mary’s Dental Practice, we use safe, dentist-prescribed whitening treatments that can brighten your smile by several shades—often reaching the brightest natural shade: B1—in just a matter of weeks.

Forget over-the-counter kits or gimmicks. This is real whitening, with real results, backed by professional care.

Frequently Asked Questions

Please reach us at stmarys.dental@hotmail.com if you cannot find an answer to your question.

How white will my teeth get?

With our treatments, many patients reach the B1 shade—the lightest natural white—within 2–3 weeks of starting treatment.

Is whitening safe?

Yes. Our whitening is clinically approved and supervised by our dental team, meaning it’s far safer and more effective than high-street kits.

Will it make my teeth sensitive?

Some patients experience mild sensitivity, but it's usually temporary. We can recommend desensitising products to help manage this.

How long does it last?

Results can last 12–24 months with good oral hygiene. You can top up periodically to maintain your brightness.

Can I get whitening if I'm on Denplan?

Yes! Denplan patients that have had whitening in the past at St Mary’s receive free whitening syringes annually—a fantastic perk included with your membership.
