Q&A for How to Whiten Teeth

Yes, it's generally safe for most people. You probably shouldn't use them if you have braces, though. You'll also want to avoid using them if you've had restorative work down, like a crown, filling, or veneer.

It kind of depends on a couple of factors. If your teeth are yellow, it's because the dentin underneath your enamel is showing through. If your enamel has been worn away, there isn't really a whole lot you can do to get the enamel back. However, you may be able to get your teeth a few shades whiter by brushing regularly, flossing, and seeing your dentist for regular cleanings. Teeth whitening strips can also help, but you shouldn't use these if you have braces or if you've had any restorative work done.

It depends firstly on your regular diet and if you consume colored foods and drinks or if you are a heavy smoker. A good final result requires not just brushing with baking soda but also a balanced diet. You can see good improvements after the first two weeks, but if you are not happy with the result then you should go for a professional whitening treatment

Baking powder contains baking soda, so the concentration is lower and the final effect is not going to be the same as if you were using plain baking soda. You can mix hydrogen peroxide with lime juice and make a paste which can be used before regular brushing. Mixing hydrogen peroxide with baking soda is also a good idea and you can leave the final mixture on your teeth for a minute or so and then simply rinse.

Brush twice a day and use mouthwash before going to bed. See your dentist twice a year for a cleaning session. Air polish combined with a fluoride gel applied in office gives a brighter tooth surface also.

First you should avoid colored drinks such as red wine, soy sauce, cola drinks and nicotine products. You can choose a visit to your dentist for a fast whitening result or trying homemade remedies that use natural ingredients; these will take longer and give you a natural whitening effect.

There is a really small percentage of people that can find themselves in this situation. Another possibility is to get veneers (prep or no prep) which can also be made out of composite or ceramic. Another solution i the option of placing dental crowns made out of white ceramic material.
