Every now and again you will need a crown replacement. A crown is a protective shell, designed to increase the life expectancy of a tooth. It fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown is sometimes known as a ‘cap’. Crowns will restore teeth that have been broken. They also support teeth that have been weakened by decay or a very large filling.
But crowns can discolour and no longer fit as your gums recede and your surrounding teeth move. So if you have teeth whitening, a discoloured crown can become more apparent. As they are unaffected by the whitening process there will be a colour contrast between teeth and crowns. However a crown replacement will correct this.
Crowns and replacement crowns are made of a variety of different materials. New materials are being introduced all the time. These are some of the most popular options:
- Porcelain bonded to precious or non-precious metal. This is what most crowns are made from. A precious or non-precious metal base is made and then porcelain is applied in layers over it.
- Porcelain crowns. These crowns are made entirely out of porcelain. They are not as strong as bonded crowns, but they look very natural. As a result, they are used for front teeth.
- All-ceramic crowns. A modern material, which is metal free. It has the strength of a bonded crown and the appearance of a porcelain crown. It it suitable for use in all areas of the mouth.
- Glass. Glass crowns look very natural. They are used on front and back teeth.
- Gold alloy crowns. Gold is one of the oldest filling materials. Today it is used with other metals to increase its strength. This makes it a very hard-wearing restoration. These crowns are silver or gold in colour.
