How long does it take for taste buds to recover?


Hello, in February I had a cold and after taking medication for several days, I suddenly noticed that food tasted bland.
Initially, I thought it was due to the cold medication affecting my sense of taste, so I stopped taking the medication, but the situation did not improve.
I can taste food, but I cannot detect salty or sweet flavors; I cannot taste sweetness at all, and I can only taste a very faint saltiness.
The sour taste is normal, but when I eat something sour, it seems even more sour.
The bitter taste is also normal.
I consulted an otolaryngologist, but the doctor mentioned that I might have over-cleaned my tongue, which could have removed my taste buds.
I usually use mouthwash and have a habit of cleaning my tongue, using mouthwash daily.
Can this really remove taste buds, or is it related to the cold?

Dr. Zheng Jueyi reply Otolaryngology


Hello: Changes in taste are often associated with inflammation of the tongue.
It is recommended to rinse your mouth only with plain water and to avoid brushing your tongue.
If there is no significant improvement in taste after two weeks, it is advisable to consult an otolaryngologist and a neurologist to examine the structure and nerve function.
Wishing you peace and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


The recovery time for taste buds after an illness can vary significantly depending on several factors, including the nature of the illness, the medications taken, and individual health conditions. In your case, it seems that you experienced a loss of taste following a cold, which is not uncommon. Viral infections, particularly those affecting the upper respiratory tract, can lead to temporary changes in taste perception, a condition known as dysgeusia.

When you mentioned that you stopped taking medication because you thought it was affecting your taste, it's important to note that some medications can indeed alter taste perception. However, in many cases, the underlying viral infection itself is the primary culprit. The inflammation caused by the virus can affect the taste buds and the olfactory system, which is closely linked to our sense of taste.
Regarding your concern about over-cleaning your tongue and potentially damaging your taste buds, it is indeed possible to irritate or damage the taste buds through excessive brushing or using harsh mouthwashes. The taste buds are delicate structures, and while regular oral hygiene is important, overzealous cleaning can lead to irritation or even a temporary reduction in taste sensitivity. If you are using a tongue scraper or brushing your tongue too vigorously, it might be wise to reduce the frequency or intensity of this practice.

In terms of recovery, taste buds generally have a good capacity for regeneration. If the loss of taste is due to a viral infection, many individuals find that their taste returns within a few weeks after the illness resolves. However, if the issue persists beyond a month, it may be advisable to consult a healthcare professional, such as an otolaryngologist, for further evaluation. They can assess whether there are any underlying issues that need to be addressed.

In summary, while it is possible that your cold and the subsequent use of medications contributed to your altered taste perception, over-cleaning your tongue could also be a factor. Taste buds typically recover well, but if you continue to experience issues, seeking medical advice would be a prudent step. Maintaining a balanced approach to oral hygiene, including gentle cleaning of the tongue and avoiding harsh products, can help protect your taste buds while ensuring good oral health.
