Hi sir..   The tasteless sensation is due to chlorhexidine mouth wash because of prolonged use......   It should not be used more than 15 days.... Discontinue the use of chlorhexidine mouth wash... you will recover with in 7_10 days.. Continuous use of chlorhexidine mouth wash also cause yellowish brown discolouration of teeth

Regular Use of mouthwash is recommended mostly for the 2 weeks. Loss of taste sensation can be a manifestation of prolonged use of mouthwash. So its better you stop using it.

Mouth washes are generally recommended for max duration of 45 days if they have chlorohexidiene. So i would advice u to stop using mouthwas and start doing warm saline rinses if u r not bp patient

Hello, Yes long term use of a mouthwash contaning chlorehexidine could alter the taste sensation. It would have been helpful if you had specified why your dentist had recommended for the usage of mouthwash. However since you have noticed this abnormality it would be wise to stop the usage of the mouthwash. Such a side effect with the mouthwash is not common however it could effect some people. Depending on the condition as to why the mouthwash was prescribed you can start with a warm saline gargle instead. After you stop the usage the taste sensation will eventually return to normal with time. Yes as u mentioned with age taste sensation does alter or reduce.

If this issue started after the mouthwash, discontinue the mouthwash for a few weeks and see how you feel. Loss of taste sensation can occur due to common viral infections, fevers etc or due to any other medication you might have taken. Wait for a few weeks. If it persists consult your dentist or a physician
