Teeth Whitening or Crowns?

Tooth whitening or tooth bleaching is perfect if you have only stained or discolored teeth. The yellow or brown surface of your teeth can be lightened by several shades and you get a dazzling smile. But if your teeth have intensive decay or damage, you may need crowns instead.

A crown, also known as “caps”, is a durable ceramic-like material that is fitted over the entire top of a tooth, which is above the gum line. A crown may be made of gold, white porcelain, or a mixture of gold and porcelain. When the crown is placed, it covers, seals, protects, and strengthens the tooth.

You will need crowns when you have a tooth decay that is too large and too deep that a filling won’t be enough. The tooth structure is also weakened that it will need additional support from a crown so that it will not eventually fall apart.

You will also need crowns for old fillings that already broke down. A crown is placed to essentially save the tooth, because once the tooth crumbles down, you may need to replace it with artificial ones.

However, if the tooth is just cracked or fractured, a crown may still save it. The crack won’t be sealed by a filling. Only a crown can hold it together and prevent the pressure of chewing from eventually breaking the tooth apart. Once the tooth is broken, a crown will be useless, especially if the break reaches the root. This is extremely painful.

A sensitive tooth may also benefit from a crown. The tooth may have become sensitive due to receding gums and due to “wear and tear” (may have been used for biting other objects aside from food). A crown can seal the tooth so that it will be protected from both cold and hot sensitivity.

If the tooth underwent a root canal therapy, it may be a good idea to use a crown to seal and further protect this tooth. A root canal therapy “kills” the tooth root by cutting off the nerve and the blood supply to this tooth. A tooth with its root desensitized won’t feel anymore pain, but it has also become brittle, and consequently prone to cracks. To prevent this, a crown is placed to strengthen the tooth.

Most of the conditions we have described, if not severe (for example, crack is only slight) may be addressed by veneers only. But teeth with big fractures will really need the protection of crowns.

Check your teeth now. Do you need teeth whitening or a crown? Maybe both?
