Teeth whitening: what to understand first
Options and their limits, existing fillings or crowns, and questions about sensitivity and cost.
2 min readStart with an assessment
Whitening lightens natural teeth; it does not address every cause of discolouration. Have your teeth and gums assessed first to check suitability. Tell the dentist about existing sensitivity, restorations and any whitening you have tried before.
A device name or a photograph is not enough to choose a procedure. Ask what can reasonably change in your case and whether whitening is the appropriate way to achieve it.
Restorations do not whiten in the same way
Whitening does not change the colour of fillings, crowns or veneers the way it changes natural teeth. A colour difference may become more noticeable afterwards, especially at the front of the mouth. Discuss this before starting rather than assuming everything will reach the same shade.
Ask about sensitivity and follow-up
Whitening can cause temporary tooth sensitivity or gum irritation, and responses differ. Ask for clear instructions on use and what to do if symptoms trouble you. Do not extend treatment time or repeat applications on your own in pursuit of a faster result.
Questions to take to the consultation
Ask which method is proposed and why, what result is realistic, whether anything needs addressing first, and what the fee and follow-up include. There is no approved fixed whitening price or duration on this website; the clinic must confirm details after assessing your case.
Case photographs help illustrate a type of change, but they do not promise the same outcome for you. Read the accompanying description rather than relying on the photograph’s colour alone.
