Cavities are caused by the attack of acids on the tooth. These acids are produced when the oral bacteria react with sugars present in our food. The acid erodes the enamel, leading to cavities. If a decayed tooth is not treated and restored in time, the damage extends to the pulp of the tooth. Root canal treatment is needed at this stage. If treatment is not administered, the tooth deteriorates further, leaving extraction as the only option.
Periodontal disease can cause bone loss around the tooth. If treatment is not done, the infection spreads further and damages the tooth beyond repair.
Sometimes, there is not enough space in the mouth for all the teeth to erupt properly. Extractions are done in such cases to help make room in the mouth and administer orthodontic treatment to properly align your teeth and bite. Such extractions are mostly performed om the premolars.
Sometimes, trauma or accident can render a tooth irreparable and extraction is the only way to restore your oral health.
Sometimes, our wisdom teeth may not erupt properly or may erupt at an angle. This creates pressure on the adjacent teeth and on the gums, leading to pain, inflammation and infection. The wisdom teeth need to be extracted in such cases.
