For teeth as white
as you want them to be

Do you dream of a whiter, cleaner smile? A simple, quick and cost-effective treatment can give you the results you have been longing for. Throw away those whitening toothpastes that don’t work. It’s time to get your teeth whitened by the professionals.

How can we whiten your teeth?

We will check to ensure your mouth is healthy and to confirm teeth whitening is the best treatment for you. We will discuss the options and any pros and cons of each.

Teeth whitening is very simple. You need professional dental bleach to touch the surface of the tooth and time for it to work.

A digital scan is taken, and custom bleaching trays are made. These trays are very important as the seal has to be very good. If there are spaces where saliva can get underneath and into the tray it will neutralize the bleach which means the teeth whitening won’t work. It can be difficult getting good impressions using conventional techniques and there are many problems associated with them. With new digital scanning the accuracy is excellent which means you get the very best bleaching trays with the best seal. We can take you from an A4 to a B1 shade and will discuss the options with you in depth.
Photos are taken to assess the starting colour of your teeth.
The bleaching trays are fitted and checked to ensure they are a perfect fit.
You will be whitening your teeth at home and we will give clear instructions on how to load up the bleach in the trays.
Every day your teeth will gradually get whiter and whiter.
Once you are happy you can stop. As the process is gradual, you are in control of how white you want your teeth to be. Typically, it will take two weeks to whiten your teeth.

The first step is to book an appointment.

  Dr Anhaar is a wonderful dentist who takes such great care of her patients. I have been attending this dental practice for 10 years. Despite moving out of the area several years ago, I still attend this practice as I know I am in great hands. I have had my teeth straightened and whitened as well as regular dental checkups and hygeines. Before becoming a patient at this practice I was afraid of going to the dentists, I genuinely enjoy my visits to the dentist seeing Dr Anhaar.

  Had a great experience here with Dr Iain. He really listened to what I wanted to achieve, and took great time in explain the options! The result is wonderfully whiter and brighter teeth and a closed gap of my 2 front teeth with exceptional composite bonding, which has given me amazing new confidence with my smile! Thank you so much, you’ve no  idea what a difference it’s made!

  I've been going to gentle dental care whitehorse road since about 2001 where its changed names and dentists over that time. The staff are always polite and well mannered and informative about procedures and routes to take if it comes to tooth removals. If your new to the area I would give them a chance as I was lucky to be greeted by a charmless sweet female dentist and assistant during my visit. And as a patient who's got a huge fan of dentists  due to childhood fear of needles I'm happy to be a patient this branch.

  Shravani is fantastic! I am thrilled with the results of my recent teeth whitening. The process took 4 weeks (should usually take  3 weeks but I had a few stubborn teeth). She was highly professional—clearly explained everything. My smile is noticeably brighter and looks amazing. Highly recommend.

Is teeth whitening right for you?

You may choose to have your teeth whitened if you:

Are conscious about the colour of your teeth
Are a smoker or ex-smoker
Want a younger smile
Have dark/yellow teeth or stained teeth
Drink a lot of tea/coffee/red wine

The whole teeth whitening process is extremely safe and does not damage your teeth at all. There are just a couple of things you should bear in mind:

Sensitivity is the biggest side effect. Your teeth may be sensitive during the teeth whitening process and it goes away as soon as you stop. We will give you tools to minimise this as much as possible.
The bleach will whiten your teeth nicely, but it won’t whiten your crowns, veneers, bridges or fillings. Therefore, it may be necessary to change them after the teeth whitening process is complete.

We will discuss this with you at your appointment, so there is nothing to worry about.

Is there anything else you can do for cleaner teeth?

You may need a hygiene appointment if you have surface stains on your teeth. This can be a very quick way in which we can improve the colour of your teeth. In addition, if there are calculus deposits, this can neutralise the bleach very quickly which means your teeth will not whiten, so it’s important we remove them first.

Some people may also be interested in straightening their teeth. Teeth whitening is included in our teeth straightening services.

Contact the team at Gentle Dental Care to discuss teeth whitening further. We can help you improve your smile and feel confident in your appearance, with cosmetic dentistry to suit everyone. Book in for a consultation and let’s see how we can be of assistance.
