Most people who lose their sense of taste from COVID-19 recover within about 10 days, with the average closer to two weeks. But the range is wide. About 79% of people regain taste within two months, while a significant minority deal with changes that last months or even years.
The Typical Recovery Timeline
In studies tracking COVID-19 patients with taste loss, the median recovery time was 10 days, and the average was roughly 14 days. That gap between the median and average tells you something important: most people bounce back quickly, but a smaller group takes much longer, pulling the average up. By the two-month mark, about four out of five people had recovered their sense of taste.
For the unlucky minority, recovery stretches far beyond that. A prospective study following patients for two full years found that 42% of those who initially lost taste during their acute infection still reported some degree of taste disturbance at the end of the follow-up period. That doesn’t necessarily mean complete taste loss for all of them. Many experience partial recovery, where some flavors come back stronger than others, or foods taste muted rather than completely flavorless.
Why COVID Affects Taste
The virus behind COVID-19 uses a specific protein on cell surfaces (called ACE2) to enter your body, and cells in your mouth, particularly on the tongue, have high levels of this protein. Once the virus gets into these cells, it can reach the nerve endings in your taste buds directly. The resulting inflammation disrupts how your taste buds work and can interfere with saliva composition, which plays a role in how you perceive flavor.
There’s also a neurological component. The virus can travel through nerve pathways and cause inflammatory damage in areas of the brain that process both taste and smell. This is one reason taste and smell loss so often occur together, and why recovery can take a long time. When the damage is limited to taste bud cells, recovery tends to be faster because those cells regenerate regularly. When inflammation reaches deeper nerve tissue, the timeline stretches.
Taste Distortion vs. Taste Loss
Not everyone experiences a clean “lost it, then got it back” arc. Some people go through a phase where tastes come back wrong. Foods might taste metallic, chemical, or just off in ways that are hard to describe. This distortion, called dysgeusia, can actually show up after initial taste loss starts improving, which catches people off guard. You think you’re getting better, then coffee suddenly tastes like burnt rubber.
Research shows that dysgeusia can persist for well over a year after the original infection. One study of post-COVID patients found that taste distortion and unusual mouth sensations were quite common more than 12 months after infection. For most people these distortions are milder than the initial total loss, but they can still make eating unpleasant and affect quality of life.
Omicron Made Taste Loss Less Common
If you were infected more recently, your odds of losing taste are significantly lower than they were during earlier waves. During the Delta variant wave, about 34% of infected people reported losing taste or smell. With Omicron, that dropped to roughly 13%. People infected with Omicron were about 77% less likely to experience this symptom compared to those with Delta.
This pattern held across multiple large studies. The shift appears related to how different variants interact with cells in the nose and mouth versus the lungs and throat. Omicron tends to cause more sore throat and upper respiratory symptoms, while earlier variants were more likely to target the nerve-rich tissues involved in taste and smell.
Who Is More Likely to Lose Taste
Women appear to be more likely to develop taste and smell dysfunction from COVID-19 than men, with women in the 30 to 40 age range showing particularly high rates. The pattern is somewhat counterintuitive: younger women report a higher prevalence of these sensory symptoms, but their cases tend to be less severe overall. Older adults, especially those over 50, also show elevated rates of post-viral sensory loss.
Disease severity during the initial infection doesn’t reliably predict whether you’ll lose taste. Plenty of people with mild COVID lose taste completely, while some hospitalized patients never do. The connection seems to depend more on where the virus concentrates in your body than on how sick you feel overall.
What Helps Recovery
The most evidence-backed approach for persistent taste and smell problems is a technique called olfactory training. Because taste and smell are so closely linked, retraining your nose often helps restore taste as well. The basic idea is simple: you deliberately sniff strong, distinct scents (like lemon, rose, clove, and eucalyptus) for about 20 seconds each, twice a day, over several months.
A modified version of this training, using 12 different scents rotated in sets of four, showed significant improvement in patients when extended to nine months. The key finding was that longer training periods produced better results, so consistency matters more than intensity. Patients who stuck with the protocol saw measurable improvement in their ability to distinguish between different scents and flavors.
Beyond formal training, many people find that regularly exposing themselves to a wide variety of strong flavors (think vinegar, citrus, herbs, spices) helps nudge recovery along. There’s no proven supplement or medication that reliably speeds up taste recovery, despite plenty of online claims about zinc or other remedies. The most effective strategy remains patience combined with deliberate, repeated sensory exposure.
