Fillings are used to fill holes (cavities) that have formed, usually as a result of decay or tooth wear. There are many types of filling, each suitable for different cavities.
Highly effective in preventing decay on the chewing surfaces of your food grinding teeth, sealants are a simple procedure in which a tooth-colored fluoride releasing material is carefully placed onto the grooves and fissures of the tooth. This effectively "seals" the deep grooves acting both as a barrier and a chemical modifier of the enamel, so when the sealant is worn off the enamel is resistant to plaque and acids.
Quick to apply, sealants hold up well under the force of normal chewing and can last several years before a reapplication is needed.
It may be determined that you need a tooth extraction for any number of reasons. Some teeth are extracted because they are severely decayed. Others may have advanced periodontal disease or are broken in a way that cannot be repaired. Other teeth may need removal because they are poorly positioned in the mouth (such as impacted teeth) or in preparation for orthodontic treatment.
The removal of a single tooth can lead to problems related to your chewing ability, problems with your jaw joint, and shifting teeth, which can have a major impact on your dental health.
To avoid these complications, your dentist will discuss alternatives to extractions as well replacement of the extracted tooth.
