There are many reasons why a patient would need a dental crown. If you have discoloration from a previous filling or need to protect what is left of a tooth, a crown may be a viable solution. Even after RCT you need a crown to protect the tooth from getting fractured.
Like all other dental treatments, the durability of your dental crown depends on how well you maintain it. Regular brushing and flossing followed by scaling at a regular interval will help to increase the longevity of crown. The average crown lasts from 5-7 years and a well to do crown can last more than 10 yrs.
There are various types of crowns available but the main categories of crowns are
Metal- This crown is made up of non-noble metals that are highly resistant to corrosion. It also requires the least amount of healthy tooth to be removed before fitting. These crowns rarely chip or break, they last the longest in terms of wear down. They can also withstand biting and chewing forces. The only drawback with the metal crown is the color.
PFM- Also known as porcelain-fused to metal crown. This crown has a metal structure connected to it. This type of crown provides a stronger bond than regular porcelain. It is extremely durable in nature. Few drawbacks are that in case of anterior teeth if u have a gum recession the dark line of metal could be more visible. Even more amount of tooth need to be removed for placing PFM crown compared to all ceramic.
All ceramic- These crowns give a life-like appearance. They can’t be distinguished from the natural teeth and are most esthetically pleasing. The crown is made of a porcelain-based material. It has a relatively high pressure strength than any other crown.
No, there won’t be any trouble while eating rather eating will become easier with the placed crown as it will increase your ability to chew. Initially, you may feel slight discomfort, but taking small bites of soft food for a few days makes the adjustment easy.
There won’t be any problems in your ability to speak but sometimes adjusting to it may take a while.
The placement of crown will take usually two appointments, the first appointment will include preparation of the tooth, surrounding the previously occupied area for crown to be placed and the impression is taken. A temporary crown is placed before you get the permanent one in the next visit.
In the second appointment we will replace the temporary crown with the permanent one, then the dentist will examine if there is any adjustment needed, additional appointments might be required for ensuring proper fit. Both the visits will take half hour to one hour.
After the permanent crown is placed it would be advisable to avoid sticky foods and hard food items for the first 24 hrs from the side crown is placed. And for the first hour no drinking water or food. After that you may eat, drink, and clean your tooth just like before.
Yes, it is possible to remove a crown after it has been permanently placed, but the crown will get damaged. It takes a few steps to remove or adjust the crown.
