Which teeth receive more protection from fluoride?

Fluoride provides significant benefits for dental health, particularly in strengthening enamel against decay. The maxillary anterior teeth, which include the incisors and canines, typically receive more protection from fluoride due to their generally greater exposure to saliva, which is rich in fluoride. This enhanced exposure can lead to improved remineralization of these teeth, as saliva helps to protect and strengthen the enamel.

Additionally, maxillary anterior teeth are usually more involved in functional use, aesthetic considerations, and are often top of mind for patients regarding preventive care, leading to more frequent fluoride applications through treatments and toothpaste. The positioning of these teeth in the dental arch also contributes to their greater exposure to dietary fluoride compared to posterior teeth, which may be less frequently exposed.

The other groups of teeth either have less frequent exposure to fluoride or benefits due to anatomical or practical reasons, such as positioning or the nature of dental treatments focused on the posterior teeth. Thus, maxillary anterior teeth are regarded as receiving more effective protection from fluoride.
