Chlorhexidine - Use | Dose | Side Effects
Chlorhexidine is a drug used as a topical antiseptic in the form of a solution for rinsing the mouth. It has antibacterial effect and prevents the formation of dental plaque - the main cause of dental caries. Chlorhexidine is used to improve the oral cavity hygiene, for the treatment and prevention of bleeding gums, for the treatment of canker sores (painful sores in the mouth) as well as for the prevention of fungal infections of the oral cavity, especially in people who wear dentures.
Chlorhexidine should not be used in the following situations:
- In children under the age of 12 unless recommended by your dentist
- After tooth extraction
- In patients with ulcer-necrotic gingivitis
Chlorhexidine must not be used elsewhere in the body other than the mouth.
It can be used only for short periods of time. Do not swallow the solution, and make sure that the solution does not come in contact with the eyes.
This drug should not be used after tooth extraction, because if the solution comes in contact with the bones it can cause necrosis of the alveolar bone!
Chlorhexidine can often cause a dark discoloration of the teeth and tongue, which create aesthetic problems in patients. This can be prevented by regular maintenance of oral hygiene and by avoiding drinking coffee and tea. Dark discoloration is usually reversible phenomenon and quickly subsides after cessation of this drug.
Dark discoloration occurs more frequently if you consume foods rich in tannins, such as:
