No, teeth do not become weak after professional whitening when it is carried out correctly. Temporary sensitivity may occur, but enamel remains intact and rehydrates naturally.
Many people worry that whitening treatments might damage or weaken their teeth. While sensitivity can occur for a short time, professional teeth whitening does not remove enamel or permanently harm tooth structure. Understanding how whitening works helps you feel confident about the safety of the procedure.
How Does Teeth Whitening Work?
Teeth Whitening Treatment Aberdeen uses active ingredients such as hydrogen peroxide or carbamide peroxide. These release oxygen molecules that break down stains inside the tooth structure. Teeth Whitening Treatment Aberdeen lightens discolouration safely and effectively without stripping away enamel when carried out correctly.
Is Professional Teeth Whitening Worth It?
Can Whitening Weaken Teeth?
When performed properly, whitening does not weaken teeth.
- Enamel remains structurally intact
- Any temporary sensitivity is usually due to enamel dehydration
- Teeth naturally rehydrate through saliva
- Strength returns once minerals are replenished
Overuse, however, may increase sensitivity.
What Is Over-Whitening?
Over-whitening occurs when treatments are repeated too often or used incorrectly.
Possible risks include:
- Increased tooth sensitivity
- Gum irritation
- Uneven colour
- Temporary enamel surface changes
Spacing treatments several months apart reduces these risks.
