Yes, taking medications too much may cause some damage to teeth and gums. Some medications can lead to dry mouth, which reduces the secretion of saliva. Saliva acts as a natural protection for the teeth. There are also medications that contain acidic or sugary substances, which may lead to tooth decay or erosion of tooth enamel.
Some examples include:
- Antidepressants and antihistamines that cause dry mouth.
- Antibiotics, such as tetracyclines, which can cause tooth discoloration.
- Asthma medications taken by inhalation may contain acidic substances that affect enamel.
Therefore, it is important to take good dental care, such as brushing teeth regularly and visiting a dentist periodically, especially when taking medications for long periodically when taking medications on an ongoing basis.
