TL;DR
A man who lost his taste and smell after COVID-19 has regained both senses after chewing specially formulated gum during a 12-week trial. The study suggests potential for treating long-term sensory loss caused by COVID.
A man who lost his sense of taste and smell following COVID-19 infection has reportedly regained both senses after participating in a clinical trial involving specially-developed chewing gum, according to researchers at the University of Nottingham.
Dr. Paul Wicks, 44, from Staffordshire, was unable to smell or taste since contracting COVID in August 2022. He participated in a 12-week decentralized clinical trial, where he chewed flavoured gums designed to stimulate brain connections related to smell and taste. After six weeks, he noticed a significant improvement, and by the end of the trial, his senses had returned to pre-COVID levels, according to his account.
The trial involved 16 participants, with 67% experiencing improved smell and 83% reporting better taste. This innovative approach highlights the potential of sensory training techniques. The specially formulated gums contained long-lasting and changing flavours, including spicy, minty, sour, and sweet, intended to retrain sensory pathways. Dr. Yang, who led the study, explained that the approach aimed to ‘train’ the brain to recognize flavours through repeated exposure.
Why It Matters
This development is significant because it offers a potential new treatment avenue for long-term anosmia (loss of smell) and ageusia (loss of taste), common symptoms in ‘long COVID’ sufferers. Restoring these senses can improve quality of life, emotional well-being, and social interactions for affected individuals.
The success of this pilot study suggests that sensory rehabilitation using targeted flavour stimulation could become a non-invasive therapy for COVID-related sensory loss, which currently has limited treatment options.

Background
Long COVID symptoms, including persistent loss of taste and smell, have affected millions globally since the pandemic began. For more on natural remedies and health insights, see related historical health stories. Previous research has indicated that these symptoms may result from nerve damage or disrupted brain connections. Learn more about how sensory functions can be affected at this site. The University of Nottingham’s study builds on emerging theories that sensory training can help recover lost functions, with the trial being among the first to test a home-based, flavour-changing chewing gum approach.

What Remains Unclear
While results are promising, it is not yet clear how long the restored senses will last or whether the treatment will be effective for all long COVID patients. The study’s small sample size and lack of long-term follow-up mean further research is needed to confirm efficacy and safety.

What’s Next
Researchers at the University of Nottingham plan to seek funding for larger, more comprehensive trials to validate these findings. They aim to determine the long-term durability of the sensory recovery and explore the treatment’s applicability to broader patient groups.

Key Questions
Can this chewing gum help all COVID-19 survivors with taste and smell loss?
It is too early to say whether the gum will work for everyone. The initial study showed positive results in a small group, but larger trials are needed to confirm effectiveness across diverse patients.
How does the chewing gum work to restore senses?
The gum contains flavours designed to stimulate neural pathways involved in smell and taste, encouraging the brain to re-establish connections that may have been damaged by COVID-19.
Is this treatment available for general use now?
No, the gum is currently experimental and available only through clinical trials. Further research is required before it can be widely recommended or marketed.
How long might it take to see results from such treatment?
In the trial, participants reported noticing improvements after approximately six weeks of regular gum chewing, but individual responses may vary.
