There are not so many people who have regular dental checkups – they tend to have them only when problems arise. This phenomenon is known as “dental emergency treatment” as opposed to “preventive treatment”. Even though such patients may think they save money by not having regular dental check-ups – it’s quite the opposite – this turns out to be a much more expensive solution. This appears to be so because numerous diseases, which may contract, have no symptoms until they reach an advanced stage. Such example can be cavities. An affected tooth shows no symptoms until the cavities are advanced and get close to “the nerve”, when a pain follows. A dentist is the one who can detect cavities at an early stage.
