While most people can get a tooth filling, there are some cases where a filling may not be the best option. As previously mentioned, if the tooth decay is too extensive or if there is not enough healthy tooth structure remaining, a dental crown may be recommended instead. In addition, individuals with certain allergies or sensitivities to dental materials may need to discuss alternative options with their dentist. It is important to consult with an experienced dental professional to determine the most appropriate treatment for your specific situation.
