Ways to prevent gagging during dental treatment

Gagging is an upsetting problem that affects some patients during dental treatment. Gagging is the sensation of choking that causes the throat to spasm and makes swallowing and breathing difficult. Dental patients who are gaggers will often avoid dental care for long periods of time, and then become more susceptible to tooth decay and other serious dental infections. Gagging may result from many routine dental procedures, but is most common during intra-oral (within the mouth) x-rays, impressions (taking molds), and for procedures that require the mouth to be held open for extended periods of time.

Most gagging problems are either mild or moderate and can be resolved if a few steps are taken. The first thing the dentist must do is to listen to the patient about their problem. A caring and concerned attitude by the dentist can often go a long way to allaying a patient’s anxiety and can significantly reduce gagging. The dentist should then find out what procedures or situations have triggered gagging in the past and see if alternative ones can be used. I have found that several techniques are highly affective for helping gaggers. I will often use a topical anesthetic spray to numb the mouth and throat which acts to reduce the gag reflex. Other methods, including the use of super-fast setting impression materials, a rubber dam (a barrier that blocks fluids and other particles from entering the mouth), and nitrous oxide gas (Article: Patient Benefits Laughing Gas) can significantly control gagging in most patients.

Some gagging problems are severe and difficult to treat even by the most experienced dentists. These patients will often suffer from dental phobia (Article: How Dental Fears Work), and avoid dental treatment except when in severe pain. To treat a severe gagger, the dentist should first employ the same measures used for mild to moderate gaggers and also be extremely patient. The dentist may also consider having a patient lift his or her legs up off the dental chair during dental treatment, and provide that treatment in short increments. For severe gaggers who cannot tolerate intra-oral x-rays, a panoramic x-ray which keeps the film outside the mouth can be used. In some situations, unconventional measures may be required. I once had to take an impression with the patient standing up to help defeat the gag reflex. As a last resort, severe gaggers can have dental treatment performed at a hospital under IV sedation or general anesthesia.
