Soreness may be due to infection, or some irritation. Avoiding excessive alcohol and tobacco use can greatly reduce the risk of most oral cancers. Smoothing rough edges from broken teeth or fillings is another preventive measure. Maintain good oral hygiene, that includes regular examinations and thorough home care, including daily home fluoride applications hope this information has been both informative and helpful for you.
