Usually the more plaque you have the longer it stays on the teeth
And the more often you have sugar, the more damage can be caused.
At first, this damage may not be visible to the untrained eye. A dentist may be able to see a slight change in colour – amazingly the tooth may appear whiter where decay is about to occur!
When a hole is visible there may be more decay lurking beneath the surface – think of the tip of the iceberg. Fortunately we can check the degree of damage with x-rays or transillumination prior to any treatment to fix problem.
