Teeth Whitening FAQ

Are you thinking about whitening your smile? At Centre for Dentistry, here are some of the most common questions we’re asked by our Ferntree Gully and Brighton patients about bleaching their teeth:


Is a professional treatment really more effective than an over the counter product? Why?

Yes. Our teeth whitening products use concentrations that are only administered by dentists. Over the counter products use weaker concentrations that are safer for people that haven’t received a dental screening. It’s much like how prescription drugs compare to over the counter medication.


Why does whitening make my teeth sensitive?

Tooth sensitivity is a common side effect of teeth whitening. We will recommend an appropriate strength of gel to minimize irritation. You can also use a sensitivity toothpaste to reduce symptoms.


How do I make my results last longer?

Avoid foods and drinks that can stain your teeth or consider drinking them through a straw. If you have a take home whitening kit, we recommend touching up every 3-4 months, or at least after every cleaning.


Can I bleach my dental crowns?

No. Dental work like crowns, bonding, or fillings cannot be bleached to a lighter colour. If you’re thinking of getting new dental work but know you want your teeth to eventually be whiter, it’s best to whiten your teeth first and have the new restoration made to match.


Why does my whitening look uneven?

At the beginning of your tooth whitening treatment, you may notice some areas of your teeth brightening faster than others. Complete your treatment as directed and the surrounding areas will begin to blend in as they whiten in their own time.
