There are 4 main reasons why a tooth may require an extraction
After you've had a tooth extracted, it is imperative that the space be filled, in some way, to avoid a number of potential problems. Teeth are very important in maintaining your health and supporting your facial structure. Without teeth, your bone shrinks and the skin collapses, causing premature aging. Even removing just one tooth can create a high risk if it is not taken care of properly. Over time, major problems can begin to occur to the surrounding teeth and tissue. When a tooth is missing, the tooth behind the space tips forward and the opposing tooth grows down or up into the space that is there. Crooked teeth cause bite problems and can affect the ability to chew, as well as increase your susceptibility to gum disease. Forces are transferred to the other teeth, resulting in compromised support, increased wear, and deterioration. The bone begins to shrink where the tooth used to be and over time can result in facial collapse.
Replacing missing teeth can help prevent many of these consequences, and provide you many long-term benefits with improved health.
