Appointments are about 1-1.5 hours max
No two teeth are the same. Think of them like fingerprints, unique to you. Therefore results will vary person to person and can lift your teeth up to 18 shades brighter!
Your life style plays a big role in how long your whitening lasts. Generally results can last anywhere between 6 months - 2 years. If you expose your teeth to things that stain them on a regular basis, your whitening may not last as long.
The best way to prevent tooth staining is to have good oral hygiene. Brushing and flossing twice a day will keep those teeth pearly white! Drink beverages that are likely to stain your teeth through a straw and rinse with water after will help prevent stains from coming back so quickly.
Foods, beverages, habits and poor dental hygiene will play a part in staining your teeth. Smoking, chewing tobacco, drinking coffee/tea, red wine and dark sodas are the most common. Using a straw for these beverages will minimize the contact with your teeth especially after treatment.
Some people can experience some tooth sensitivity during the first 24-48 hours but it is uncommon. Those that already have sensitive teeth, cracked teeth, micro cracks, untreated cavities, leaking fillings or other dental conditions may experience increased sensitivity.
Sensodyne ís the best toothpaste to be using if you have any sensitivity. Brush your teeth with this toothpaste until your sensitivity goes away. For best results brush your teeth and do not rinse with water after. (Best to do at night) This allows the toothpaste to really works its magic and relieve any discomfort.
A white diet is recommened for 24-48 hours after your appointment. When you do any kind of bleaching/whitening your teeth are EXTREMELY porous. Avoiding things that stain them during this time is important to avoid any staining or discoloration. Once the pores close (24-48 hours) you can resume normal habits.
Think foods that are exactly that, white! (lol). Some examples are Chicken/Turkey, fish, rice. pasta (without the sauce), white cheese, eggs/egg whites, potatoes and bread.
That is entirely up to you! Most people whiten their teeth 1-2x a year or around events they want to look their best for! Schedule as you see fit :)
Teeth whitening only improves the shade of our natural teeth so the answer would be no. However, it is possible for teeth whitening to remove the stains off them yet won't brighten them any lighter than the original shade chosen.
