Teeth Whitening

What is Tooth Whitening?

Tooth whitening is way of lightening the natural colour of the teeth without removing any of the tooth structure. It cannot make the teeth ‘ceramic white’ but can certainly lighten the existing shade one or two degrees.

What does it involve?

At LPID we offer two types of tooth whitening: in surgery (laser) whitening and home whitening.

In surgery (laser) Whitening

A whitening product is applied carefully to the teeth and a light is shone on them to activate the solution. This process usually takes 1 hour and may require home whitening after.

Home Whitening

Involves taking a mould of the teeth to make the tooth whitening tray.

A whitening solution is applied to the tray and worn for 1-2 hours at home for 14 days. This process may be repeated depending on results.

The active ingredient in tooth whitening is hydrogen peroxide or carbamide peroxide. As the active ingredient breaks down the oxygen molecules move into the enamel making them lighten.

How long does it last?

The effects of tooth whitening may last up to three years, but this depends on person to person. The effects are less likely to last if you smoke, drink and eat high staining products.

What are the side effects?

Some people may experience some sensitivity to cold during and after treatment which is easily managed with desensitising toothpaste. Others may experience discomfit to gums, sore throat and white patches. The symptoms are usually temporary and should disappear.

Our team will go over the side effects and how minimise them during the visit.

What about home whitening kits and whitening toothpaste?

There are many home whitening kits and tooth paste available on the market which may involve whitening strips and paints. The effectiveness of these depends on the percentage of whitening agent they contain.

Home kits may be cheaper, but they are not always assessed for health and safety and tend to be more acidic and may contain abrasives. This may be damaging to the teeth and gums.

Home kits and toothpastes sold in Europe must only contain up to 0.1% peroxide which is too little to be effective.
