When it comes to teeth whitening, many people wonder if whitening procedures are effective in whitening the back of the teeth. While it is true that whitening procedures can significantly improve the appearance of the front teeth, they may not have the same impact on the back teeth. In this article, we will explore why whitening procedures may not whiten the back of your teeth and discuss alternative options for achieving a brighter smile.
The Anatomy of Tooth Stains
To understand why whitening procedures may not be as effective on the back teeth, it is important to understand the anatomy of tooth stains. Tooth stains can be categorized into two types: extrinsic and intrinsic stains. Extrinsic stains occur on the surface of the teeth and are typically caused by substances like coffee, tea, and tobacco. Intrinsic stains, on the other hand, occur within the tooth and are often a result of aging, certain medications, or trauma.
While whitening procedures are effective in targeting extrinsic stains, they may not penetrate deep enough to reach the intrinsic stains on the back teeth. The composition of the back teeth, with their thicker enamel and deeper dentin layer, can make it more challenging for the whitening agents to effectively whiten the teeth.
Limited Coverage of Whitening Trays and Strips
Whitening trays and strips, which are commonly used for at-home whitening, may provide uneven coverage on the back teeth. The shape of these whitening tools is designed to fit the front teeth more comfortably, resulting in less contact and coverage on the back teeth.
Furthermore, the curvature of the teeth may cause the whitening gel or strip to slide off the back teeth, reducing its effectiveness. As a result, while the front teeth may appear noticeably whiter after using whitening trays or strips, the back teeth may not experience the same level of whitening.
Veneers and Bonding as Alternative Options
If you are looking to whiten the back teeth, alternative options such as veneers and bonding may be worth considering. Veneers are thin shells that are custom-made to fit over the front surface of the teeth. They can be made to match the desired shade of whiteness and provide a uniform appearance across all teeth.
Bonding, on the other hand, involves the application of a tooth-colored resin material to the surface of the teeth. This procedure can effectively cover stains and discoloration on both the front and back teeth, providing a brighter smile overall.
Pricing of Teeth Whitening Procedures
Teeth whitening procedures can vary in price depending on the method and location. On average, professional in-office whitening can cost between $500 and $1,000. At-home whitening options, such as whitening trays and strips, can range from $20 to $200, depending on the brand and effectiveness.
For veneers and bonding, the price can vary significantly depending on the dentist and individual case. On average, veneers can cost between $500 and $2,500 per tooth, while bonding can range from $100 to $400 per tooth.
