There are several options available if you want to whiten your teeth. While there are many whitening toothpastes and rinses available, their strength and effectiveness are limited, and most any toothpaste will do essentially the same thing.
Bleaching strips can be cumbersome to use, and they usually only whiten the front six teeth. If your back teeth are capped, this may be a good alternative.
Many over-the-counter whitening products are more effective than toothpastes, but typically their chemistry is either very weak and cannot bleach the teeth for sufficient amounts of time, or they are very strong and dangerous to use and ingest.
Your dentist is still the best option. Whitening done at the dentist’s office is much more controlled, and produces better results.
Professional teeth whiteners are safe, effective, and done under the supervision of a dental professional. In most cases, it is worth the extra cost to visit the dentist to get long-lasting, safe results.
