Teeth whitening treatments can lift intrinsic stains from beneath your tooth enamel, and remove extrinsic stains from the outside, giving you a brighter whiter smile. But they won’t keep your teeth white forever – you’ll need to make some lifestyle modifications and go for top up treatments to preserve the brightness of your pearly whites. Let’s look for some tips on how to keep your teeth white for longer once you have had a whitening treatment.
Why Do Teeth Become Discoloured?
If you’ve ever tried teeth whitening strips or an at-home toothpaste and felt underwhelmed by the results, it would probably help you to know that a great deal of discolouration is actually taking place inside your teeth, under the dental enamel. While substances like red wine and coffee can cause external or extrinsic stains, intrinsic discolouration is actually part of the ageing process.
As we get older the dentin inside the teeth changes from white and becomes more yellow. There are no home remedies or natural ingredients that can lift stains from under the tooth enamel and only professional teeth whitening treatments can whiten and brighten your teeth.
How To Keep Teeth White Safely?
If you’d like a tip on how to keep teeth white safely, remember that only professional grade teeth whitening treatments are strong enough to penetrate tooth enamel but do it safely enough not to cause damage. While some over-the-counter or store bought products might be effective at removing extrinsic stains, they can contain abrasive substances and actually cause damage.
Substances like baking powder, lemon juice and even charcoal are sometimes listed as effective natural ingredients on home whitening kits but in many instances they can cause more harm than good.
Your dentist is certified to administer teeth whitening products that contain more than 6% hydrogen peroxide, which achieves better results faster.
Typically you will have a pre-whitening consultation and check-up where your dentist will tell you what kind of results you can achieve from a treatment. Your gums and teeth will be checked to ensure they are free of gum disease and decay and your dental practitioner will make recommendations on the most appropriate course of treatment.
How Does In-chair Teeth Whitening Work?
In-chair teeth whitening gives the fastest results and allows your dentist to be in full control of the process. Once your teeth have been inspected, your dentist will paint a thin layer of bleaching agent over the surface of your teeth. Some whitening products need to have a blue light shone onto them to activate the bleaching agent. The whitening gel will be left on for 10-15 minutes before being removed. If need be, your dentist may apply another layer.
How Do Take-home Trays Work?
If you decide that in-chair teeth whitening isn’t for you, you will have the option of take-home trays which are customised to your mouth and teeth. You will wear the trays for the period of time prescribed by your dentist until you achieve your desired results.
