will teeth whitening make my teeth sensitive??

It is normal to have some sort of sensitivity around 12 hours afterwards in most cases. Your teeth will go to your natural white colour, never beyond that.. If done properly you should notice a difference . Regarding sensitivity there are things you can do before and after a treatment such as taking nurocen and use a sensodyne toothpaste.
We also like to use a desentisising gel afterwards. That also helps with sensitivity issues.

You should check for products which are hydrogen peroxide free. I can recommend Stella white strips ;)

It is not uncommon to experience tooth sensitivity and / or gum irritation whilst whitening your teeth. This is temporary and not harmful. Whitening treatments that use stronger whitening gel are more likely to lead to sensitivity. Also, if you have receding gums then you are more likely to experience tooth sensitivity. Sensitivity from whitening is temporary and will subside. You can use sensitive toothpastes to minimize the sensitivity or you can use a desensitizing gel.
Whitening treatments that are carried out in one sitting use higher strength whitening gel and therefore lead to higher rates of sensitivity. You may prefer to use dentist supplied teeth whitening strips because they use normal strength whitening gel and the optimum amount of whitening gel is already applied to the strips so you don't need to worry about too much gel being applied (which is a common reason for sensitivity as well).

All I can say is go the natural way... avoid drinking colourful drinks ( red wine! ) and if you have to use a straw, it might look silly but keeping your teeth naturally white is a plus!

Hi Rachael, its perfectly normal when having your teeth whitened to experience a little sensitivity, this is however only temporary and in most cases extremely mild. I recommend you only speak to a qualified dentist when considering having your teeth whitened, then you can be assured that the opinion you are getting is based on proven professional experience, and your smile in the best possible hands.
