Is it safe to whiten teeth?

Research and clinical studies indicate that whitening teeth with either hydrogen peroxide or carbamide peroxide under the supervision of a dentist is safe for both the teeth and gums. Hydrogen peroxide and carbamide peroxide are both often used to treat infections and gum problems.

Your dentist will advise you if you are a suitable candidate for whitening.

 

Reasons for dark teeth:

Some people have naturally dark teeth but the shade can also change with diet, smoking and age. Things such as tea, coffee, red wine, curry or other highly coloured foods can stain teeth. 

During tooth-formation, consumption of tetracycline or excessive fluoride may also cause tooth discoloration.  

If a tooth gets knocked this can cause the nerve of the tooth to die off and it will probably begin to darken. It will require root canal therapy to save it.

 

Whitening of a single non-vital tooth:

When a single tooth is discoloured due to nerve degeneration, you may choose to be have it whitened. This can be done by using the non-vital tooth method where a small hole is drilled usually into the back of the tooth. A medicament is placed within the tooth to bleach it to the required shade, (this process may need to be repeated) the hole is then refilled.

 

How does whitening work?

When bleaching gel is placed in contact with the teeth the carbamide peroxide splits into hydrogen peroxide and urea, oxygen then enters the enamel of the teeth bleaches any stained areas. The structure (make-up) of the teeth does not change, only the tooth/teeth colour.

 

At home procedure:

Before teeth whitening can commence it is vital that your mouth is in excellent health. We recommend that you visit one of our dentists or hygienists first, as often a scale and or polish is required prior to any home whitening.

 

This will require impressions to be taken first for the bleaching trays to be made specifically for you.

Whitening trays are usually ready for you to collect within a day or two, along with the bleaching material and full instructions.  This treatment is done by applying whitening gel to your trays for anywhere between 2 to 8 hours daily for around 3-10 days or as instructed by your dentist or hygienist.

 A take home pack is provided for you along with your mouth trays and whitening gel, which will be available for collection within a day or two.

 

After any whitening procedure is it advisable to refrain from eating or drinking any foods (for 48 hours) which may stain the teeth, such as red wine, tea, coffee, carrot juice or curry.
