Why are certain teeth in need of dental crowns?

 

A dental crown may be required for a number of reasons. Because a dental crown replaces a tooth's enamel coating, the usual response is that a tooth requires a dental crown when the enamel no longer serves its purpose. Enamel is the human body's toughest material, built to endure the temperature, chemical, and mechanical pressures that our teeth experience when we eat and drink. Unfortunately, it is not impenetrable. 

Cracking, acid erosion, and degradation are all possibilities with enamel (cavities). All of these things may necessitate the use of a crown. The following are the most prevalent reasons why a tooth may need dental crown protection. 

1. Big Cavities 

Cavities are bacterial infections of the enamel and other hard materials that comprise each tooth. Germs consume sugar and create acid, which dissolves enamel and allows bacteria to enter the tooth. A cavity weakens and compromises the enamel, causing it to no longer sustain appropriate chewing function. Your dentist will assess the extent of a cavity as well as the amount of good tooth structure left to decide whether the tooth needs a filling or a dental crown. In many circumstances, the cavity is so big that the remaining tooth structure cannot sustain a filling. 

2. Massive Fillings 

A big filling on a tooth may need the placement of a dental crown. While a filling is an excellent way to repair tooth structure lost due to disease, it does not strengthen the tooth. It merely fills the gap. A crown may be required to avoid future damage when a filling is big and covers more than half of the exposed tooth. 

3. Serious Acid Erosion 

Patients with severe acid reflux or GERD, or those who have acidic habits (such as consuming sodas on a regular basis), may lose considerable amounts of enamel via erosion. Rebuilding these teeth and restoring damaged enamel is required to avoid further damage and potentially tooth loss. 

4. Enamel Loss from Heavy Clenching/Grinding 

Mechanical wear and tear from clenching and/or grinding during sleep is another source of substantial enamel loss, check this website for more information. As the enamel gradually wears away, the teeth shorten and flatten. Rebuilding these teeth, like preventing acid erosion, can avoid additional damage and ultimate tooth loss.

5. Chipped Teeth 

While cracks are more prone to form on teeth with big fillings, they may also occur in apparently healthy teeth. Cracks in the back molars of those who clench or grind their teeth at night are prevalent. They may also be caused by trauma, such as biting into a hard, foreign item. When a tooth cracks, the break in the enamel enables temperature sensations as well as microorganisms to enter the tooth. Cavities and sensitivity to cold and/or chewing forces are often the result of a fracture. 

6. Root Canal Therapy 

Finally, a tooth that has had a root canal normally requires complete covering with a dental crown. This is due to the removal of nerves and blood supply from the hollow chamber of a tooth during root canal procedures. Teeth become fragile and easily broken when they lack a blood supply. Because root canal treated teeth do not have a nerve inside, they do not feel the symptoms of a broken tooth, thus patients often overlook the warning indications of a problem. A crown is required to protect the tooth after a root canal treatment to prevent it from breaking.
