I've made an appointment to talk to the dentist about teeth whitening. The cost is apparently £400. I'm thinking of giving myself a Christmas present
. My teeth are basically in good condition (no fillings at 51!) but old and yellow/stained.
-What questions should I be asking?
-Are there different types and are some better (or safer?) than others?
-How does what the dentist gives you differ from DIY kits and is it superior enough to justify the cost?
-Does £400 sound about right?
Thank you!
