Teeth whitening in Polokwane

Teeth whitening is a treatment aimed at lightening the shade of natural teeth. It works on the enamel and dentine that make up the tooth, rather than on deposits on the surface, which is why it is a different process from a cleaning. Where a cleaning removes build-up so teeth look their natural clean, whitening aims to change the colour of the tooth itself.

Whitening is considered for a range of reasons — staining from food, drinks, or tobacco, or a general dulling of colour over time. Not all discolouration responds the same way: some types lighten readily, while others, such as discoloration from certain medications or from the nerve inside the tooth, may need a different approach. This is why an assessment comes before any whitening.

Before whitening, a dentist assesses the teeth and gums to check that the mouth is healthy enough for the treatment and to judge what kind of result is realistic. Existing decay, gum inflammation, or sensitive areas may need attention first, because whitening over an unhealthy mouth can cause problems.

The assessment also looks at existing restorations — fillings, crowns, bridges — because whitening does not change the colour of these materials. If restorations are visible in the smile, their colour is part of the conversation, since they will not lighten along with the natural teeth. The plan is built around what is actually in your mouth.

Whitening affects natural teeth but not restorative materials. A filling, crown, or bridge that was matched to the colour of the teeth at the time it was made will stay its original shade, so after whitening it may appear darker by comparison. Where that matters in the smile, replacing or adjusting restorations may be discussed afterwards.

This is one of the reasons the assessment matters: understanding which teeth will lighten and which will not lets you plan the result rather than be surprised by it. The conversation about restorations is part of planning the whitening, not a separate concern to raise after the fact.

How much a shade can be lightened, and how quickly, varies from person to person and depends on the starting colour and the cause of the discolouration. Whitening is not a way to reach a single 'ideal' shade for everyone; it is a change within the range your teeth allow. Realistic expectations are part of a good result.

Some people experience sensitivity during or after whitening, which is usually temporary. How it is managed — and whether it is likely in your case — is worth discussing beforehand. Useful questions to bring include what is suitable and what to expect.
