The short explanation
Teeth whitening done by a dentist is generally considered safe for healthy teeth, but temporary sensitivity is a common side effect. The whitening agents can make teeth sensitive to cold or hot for a short time, which usually settles after treatment ends. Gums may also feel irritated briefly. Before whitening, a dentist will check for decay, gum disease, cracks or exposed roots, which can make sensitivity worse or need treatment first. Over-the-counter whitening kits and home remedies like lemon or baking soda can damage enamel and gums, so they are better avoided.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Fillings, crowns and veneers do not whiten, so colour may not match.
- Results vary, and whitening does not last forever.
- Plan whitening well before the wedding, in case sensitivity occurs.
- Ask about costs and what is included.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether whitening is suitable for your teeth. A dentist needs to examine you.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Are my teeth suitable for whitening?
