Oral Surgery | Extractions
There are a few reasons why we may decide to remove a tooth. A tooth extraction might be necessary when a tooth is damaged beyond practical repair. The conditions that warrant extraction are usually so extreme that regular reconstructive work (i.e. fillings, crowns, etc.) will not be effective. There are several other factors that can play into the decision of pulling out a tooth, such as long-term treatment and cost of repair. Sometimes extraction is easier and more cost effective than reconstruction.
Severe damage to the gums may also necessitate dental extraction. As gum disease gets worse, the tooth loses the support of the surrounding bone and becomes loose. The gums can no longer hold it in place. In cases where the bone and/or tooth have become excessively damaged, extraction of the tooth may be necessary.
Teeth that are not well positioned or nonfunctional may also need to be extracted. Sometimes the extraction of healthy teeth is required for good oral hygiene. Some teeth that are badly positioned to the point of pain and irritation may need to be extracted simply to alleviate the pain and to prevent further misalignment of other teeth.
Wisdom teeth often fall into this category. The wisdom teeth are at the back of the mouth and are often difficult to clean. This can lead to cavities, tooth decay and gum disease. Usually, it is simply easier to extract the wisdom teeth as a preventative measure against future problems.
Many times, the wisdom teeth are “impacted” which means that they are in such misalignment that they cannot emerge from the gums in proper or even effective alignment. In some cases, they may even push against other teeth causing the entire mouth to become misaligned. Extracting impacted wisdom teeth can help keep all the teeth in proper alignment.
Often, when orthodontic treatment is required, some teeth, including the wisdom teeth, may need to be extracted to improve the alignment of the teeth. When the size or number of a person’s teeth is not in proportion to a person’s jaw, the strategic extraction of some teeth may be necessary.
With the advent of Invisalign, extractions for orthodontic reasons are dramatically reducing. This is because we use 3D imaging to calculate on computer the exact space requirement (accurate to one tenth of a millimeter) and are finding that traditional space creation methods of extraction, actually yield far greater space than is actually required.
Extractions are routinely performed painlessly under local anaesthetic. For surgical extractions and for nervous patients, Sleep Dentistry will be offered as an alternative. Through discussion with us, we will always find a method that gives you the best outcome with as much comfort as possible. Welcome to dentistry Siana Dental style!
Bone Preservation (after an extraction)
Following a tooth extraction, bone and soft tissue tend to shrink if no measures are taken. This can leave insufficient bone volume to later fix an implant, or may cause a gap under a dental bridge.
Filling the extraction socket with a bone substitute directly after tooth extraction can preserve bone volume, which increases the options for successful further treatment. If a dental implant is inserted soon after tooth extraction, bone substitutes placed around the implant also contribute to bone volume maintenance.
