The question of "do dentists lie about cavities" is a serious one, with potential implications for the trust between patients and dentists. While there is no one-size-fits-all answer, it is important to be aware of the potential for dishonest or unethical behavior in any profession, including dentistry.
There are a number of reasons why a dentist might lie about cavities. Some dentists may simply be trying to make more money by convincing patients that they need unnecessary treatment. Others may be afraid of losing patients if they tell them the truth about their oral health. Still others may simply be mistaken about the presence or severity of a cavity.
