Gagging and Dentures. Testing Palatal and Gag Reflexes in Preparation for Denture Treatment.

by Dr. Alexander Shor

August 4th, 2013

dentures and Gagging Alexander Shor DmdPatients who consider denture treatment and have gagging problems should be carefully evaluated for the extent and severity of their palatal and gag reflexes.

For clarification gagging is a layman’s term and  what we are talking here are  Palatal and Gag (also called Pharyngeal) Reflexes.

Almost all people react to the tactile (touch) stimulation on the palate and throat by contracting their palatal and throat muscles. The degree of muscle contraction can vary from minor to severe. In addition to  muscle contractions some people may also react with retching, coughing, eye watering, excessive salivation and vomiting. When a person have these reactions we call it an exaggerated reflex.

Exaggerated reflex is very important consideration in denture treatment, especially with the top  denture becasue it rests on the palatal tissues. In a sensitive person denture can be very uncomfortable and she or he will not be able to tolerate the denture if it extends into the sensitive area.

Over the years I have seen a number of patients who received denture treatment and could not use their dentures because of  the exaggerated reflex. Some of these patients were unhappy because their gagging problem was not discovered at the beginning of the treatment.

I usually ask patients who consider denture treatment if they experienced any gagging problems. Patients with severe form of  gagging are very aware of this problem. What we are more concerned are the patients with mild to moderate form of exaggerated reflex and who are not sure how severe is their gagging.

If there is any suspicion of the exaggerated reflex I will perform a tactile test and in many instances will  fabricate a trial appliance. The purpose of the appliance is to simulate coverage of the oral tissues by the denture. I will ask patient to take it home and try to use it. Appliance can be adjusted so it gives us an idea on how much we can extend the denture.  An appliance can also be used as a training device and help patient with adaptation to the denture. In some situations by using an appliance we may discover that the denture is contraindicated and patient should consider other treatment options.

Below is an example of palatal appliace for a patient with a suspected exaggerated reflex. This patient presented with hopeless teeth and was considering immediate full upper denture which rests on the palatal tissues. During interview patient confirmed history of gagging. The patient was given an upper appliance and was asked to use it several hours during the day. Patient was able to adjust to the appliance and we made a decision to proceed with immediate denture treatment.

    I had my teeth pulled and got an upper denture, but am having severe gagging as to where I can’t wear my upper denture with out gagging and having to take them out. What can I do now that my real teeth are gone? (teeth pulled 7/2013 and denture received)

  • Marlene Trithardt says:

    OMG I thought it was just me that gagged on dentures. This is my second set in a year and it isn’t any better. I find it like a foreign object it in my mouth and after 3 hours I have to remove the dentures as they will make me gag after that. Is there anything that can be done? I can not live like this!

    • Hi Marlene,
      Sorry to hear about your problems. Yes, for some patients with gagging problems dentures can be very challenging. In your situation I would consider dental implants for the support of the prosthesis. With implants a prosthesis can be designed in such manner that it does not extend into the areas which cause gagging problems. Consider seeing a prosthodontist or local dentist who is specializing in dental implant restorations.
      Best Wishes,
      Dr. Shor

    I suffered terrible gagging reflex during the denture process and feared the worst during the impression stage as I constantly had issues and thought it would be the same when I had dentures. But in my case I was lucky as although initially when the dentures were put in at the dentists I had gagging issues I managed to get it under control within 48 hours when I was back home and more comfortable in my own surroundings. But I do wish a device like you show had been available to me to try out before as it would have certainly helped to calm my fears and get the gagging under control.

    Andy.
