When Are Dental Crowns A Good Choice?
Where damage to a person’s teeth is extreme, and apparently beyond repair, we can use porcelain or porcelain “pasted on gold” crowns to make the smile appear “as new”.
This is an extremely reliable technique for repairing the most severe of dental problems, even permanently replacing missing teeth to offer a complete smile and a functional bite.
These treatments are used for a long-lasting correction of major dental problems. It is usual for these treatments to last for 20 to 30 years, which is as close to permanent as dental treatment can get.
Key Benefits Of Dental Crowns
- Replaces missing teeth
- Offers support to misshapen teeth or badly broken teeth
- Looks completely natural
- Fixes “smile” and functional chewing problems
How Are Dental Crowns Made
Having a crown made usually takes two visits. The first visit is for preparation of the tooth and the second is for insertion of the newly made crown. Inbetween these visits a temporary crown is fitted so you can chew normally.
After the area is numbed with local anaesthetic, the tooth is shaped using a drill, making it smaller by on to two milimetres. After shaping, another impression is taken to record changes to the prepared tooth. The impressions are sent to a dental technician who makes the crowns according to specifications provided by the dentist. To protect the prepared tooth a temporary crown is attatched to the reshaped tooth with temporary cement. As a temporary crown is not as strong as the final crown, you should chew on the opposite side of the mouth and avoid sticky or hard foods.
At the second appointment, the temporary crown is removed. The new crown is placed over the reshaped tooth to check that shape and colour match properly. if they do, the crown is cemented to the tooth with dental cement. Dental cement usually sets in less than one hour and reaches full strength in 24 hours. After fitting, the crown should feel comfortable and natural in your mouth. When testing your occlusion, your dentist relies partly on what you say about the feel of your bite, so yoy should mention any uncomfortable or strange sensations. Minor adjustments are often needed to achieve comfort.
Taking Care Of Your Crown
Crowns should last for many years. However, there is no lifetime guarantee. As with natural teeth, it depends on good dental hygiene, oral health and the forces you apply to your teeth. Therefore, regular dental check-ups are advisable. Crowns reguire regular flossing and brushing, with extra attention around the margins where decay is more likely.
