Crowns are a lab made prosthesis that can be use to change the shape change colour and strengthen the structure for teeth that are weakened. They can provide a high level of aesthetics and in the correct situation provide a fantastic option to certain clinical situations. They can come at a cost of sacrificing tooth tissue in order to create space for the crown to be made
With advances in modern dental technology, all-ceramic crowns are proven to be as strong and durable as metal porcelain crowns and so they are able to offer patients the best of both worlds – a long lasting and natural looking solution.
Crowns can be the ideal treatment option for the following dental situations:
- To restore badly broken teeth
- To restore teeth that have been heavily filled and become weak
- To reshape, an uneven or unsightly tooth to match your surrounding teeth
- To restore the brightness to discoloured teeth
- To protect a root treated tooth
- You have a bridge or denture which needs to be held in place
- To replace an old crown that no longer fits very well or that has become discoloured
Does it hurt to have a tooth prepared for a crown?
No. You will have a local anaesthetic and the preparation work should feel no different from a filling. If the tooth does not have a nerve, and a post crown is being prepared, then you may not needs a local anaesthetic.
How long is a dental crown expected to last?
Contrary to popular belief, dental crowns don’t last forever. But with good care they can last a long time! Current research shows that more than 90% of crowns will not require major treatment within five years, and 50 to 80% of crowns will last between 15 and 20 years.4 It’s important to remember that just like a “real” tooth, the life of your crown depends on how you care for it. You should continue to follow good dental hygiene practices including brushing twice a day, flossing, and seeing your dentist on a regular basis. If you tend to clench or grind your teeth, ask your dentist how this could affect your crown. In general, you should try to avoid chewing hard or sticky foods, which may cause your crown to break or come loose.
How will I care for my crown?
It is important to keep the crown just as clean as you would your natural teeth. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth. Brush last thing at night and at least one other time during the day with a fluoride toothpaste and clean in between your teeth with ‘interdental’ brushes.
