Gagging or fear of choking
A sensitive gag reflex is a real physical response. Tell the team early so they can discuss practical adjustments and suitable care options.

Gagging is a reflex, not a choice
The gag reflex helps protect the airway. Touch, sensations near the back of the mouth and anxiety can all be relevant, and fear of choking may add to the distress.
Reducing pressure and improving control may help some people, but gagging varies and should be discussed with the dental team rather than treated as anxiety alone.
Practical things that help
If nasal breathing is comfortable for you, it may help you feel steadier. Ask which positioning and breaks are safe for the procedure, and agree a stop signal. Different approaches suit different people.
For impressions or X-rays that trigger gagging, ask what alternatives or adjustments are available. Sedation may be considered for some people after an individual assessment, alongside non-drug approaches.
Tell the team before you sit down
Telling the team in advance gives them time to discuss suitable adjustments. You can mention gagging at booking without having to explain it in detail.
Things you can try
- Practise slow nasal breathing at home so it is familiar when you need it.
- Agree a stop signal so you can pause the moment you feel the reflex building.
- Mention the gag reflex when booking, and ask what adaptations the practice can offer.
