When a whitening product is applied to the teeth, it breaks down into water and oxygen ions. The oxygen ions enter the enamel and attack the long stain molecules to effectively break them down to be short and colorless. These short and colorless molecules are then naturally removed from the tooth by saliva. The intensity of whitening is related to the number of oxygen ions available and the length of time they are on the tooth. There are various forms of tooth discoloration that can be whitened, including:
- Food
- Beverages
- Smoking
- Ageing
- Disease
- Medical treatment
- Poor oral hygiene
- Genetic conditions
- Fluorosis
- Some medications
- Some Illnesses
A whitening maintenance plan helps prevent the re-occurring build-up of stain molecules, ensuring your teeth are always looking their best. Speak to your dentist on the best maintenance program to suit you.
