Drugs That Turn Your Teeth Brown

Posted on 11/21/2022 by Thomas Plunkett DMD
Drugs That Turn Your Teeth BrownWhen we suffer from different ailments, we turn to medications to help treat these ailments. However, some medicine consists of compounds that, when in contact with the enamel, cause staining. It is okay to consult your doctor on alternative medication if this poses an issue. Below is some medicine to be careful of:


Antibiotics like tetracycline and doxycycline. They are both used to treat a wide range of bacterial infections and acne. Due to these antibiotics mainly affecting children's teeth in their formative years, children and pregnant women are more at risk of their effects. Expectant mothers should avoid tetracycline and doxycycline because they can affect the teeth of their yet-unborn babies during teeth development.


Antihistamine medication is usually used to relieve allergic reactions. Regular use of antihistamines eventually causes tooth discoloration. This happens because antihistamines reduce saliva production. Saliva is an important component of oral health as it creates a barrier against which bacteria cannot adhere to the tooth enamel. It, therefore, breaks down bacteria which can be responsible for teeth discoloration and when antihistamines suppress that, staining of the teeth will eventually happen.

Hypertension Medication

Hypertension medication is used to treat high blood pressure. Medicines like calcium channel blockers, beta-blockers, diuretics and heart rhythm medications can cause a dry mouth. As with antihistamine medication, less saliva in the mouth will directly correlate with teeth discoloration. Additionally, a dry mouth impacts swallowing and digestion negatively. Therefore a lot of food residue is left in the mouth, eventually causing tooth staining and encouraging plaque formation.

Anti-psychotic Medication

Anti-psychotic medication is normally used to treat mental health problems characterized by psychosis, such as schizophrenia. This medication has been observed to cause hyposalivation, producing less saliva than normal. Like with antihistamines and hypertension medication, this eventually leads to tooth discoloration.
