Denture Discomfort: Causes of a Covered Palate, Slipping, Pressure Pain, and Speech Changes, and Adjustment (Relining)

Why are dentures uncomfortable?

Most denture discomfort is explained by three factors: impression accuracy, jawbone resorption, and fit [2]. Typical symptoms are altered taste and a foreign-object feeling from the covered palate, rattling and slipping, pressure pain, and speech changes [2]. DentStat analyzed 540 patient comments about denture discomfort and side effects on YouTube dental content and found repeated questions about slipping, the palate, pressure pain, speech, and temporary denture discomfort, from both current denture users and family members caring for them [4].

My upper denture covers my palate and I cannot taste food

Upper complete dentures are designed to cover the palate, which can affect taste and the feeling of a foreign object [2]. Depending on gum shape and retention, a palate-free design that covers less of the palate or an implant-secured method is sometimes considered for improvement, but whether this is possible depends on examination of the jawbone and suction conditions [2]. The palate cannot be left open in every case, so the choice of method is a matter for consultation based on oral examination results [1].

My dentures keep slipping and wobbling

Slipping and rattling are often caused by impression accuracy, the seal of the denture’s inner surface, and the degree of jawbone resorption [2]. Lower complete dentures in particular are affected by movement of the tongue and cheeks and by saliva, so retention tends to be harder to achieve than in the upper jaw [2]. Rather than relying on adhesive, approaches that address the cause are considered, such as relining to refill the inner surface, remaking, or suction or implant retention [2]. Because the jawbone gradually resorbs, even a denture that fit well at first can become loose over time, and for this reason dentures are not a one-time fabrication but a prosthesis that assumes regular checkups [1].

What can be done about pressure pain?

Pressure pain is commonly caused by poor fit or jawbone resorption, and adjusting the area that presses can improve it [2]. If repeated adjustments only help briefly, the impressions and bite are reassessed or a remake is considered [2]. If the pain continues and you simply stop wearing the denture without addressing it, the gums can change so that the denture fits even worse when you wear it again, so getting it adjusted at the clinic that made it is the safe procedure [1]. Awkward speech or a feeling that the shape of the face has changed is also commonly handled through the adaptation period and bite adjustment, and for the first few days, practicing reading aloud sometimes helps with adapting [2].

Is discomfort with new or temporary dentures normal?

New dentures usually need an adjustment period, and temporary dentures are temporary prostheses meant to maintain appearance and speech, so their chewing function is limited [2]. Temporary dentures used during implant treatment are worn while the gums are swollen or healing, so a poor fit is actually common, and they are used on the assumption that they will be readjusted [2]. However, if pain or discomfort continues, do not dismiss it as “just how it is”; getting an adjustment is the safe approach. If a remake is needed, the cycle and exceptions for covered dentures should be checked against National Health Insurance criteria [3].

What are common misconceptions about discomfort?

Beliefs such as “slipping dentures cannot be helped, so you have to rely on adhesive” or “if they do not stay in, it is an adhesive problem” are not accurate [2]. Retention depends on impression accuracy, the suction surface, and jawbone condition, so addressing the cause can improve it in some cases [2]. Expectations such as “upper dentures must always cover the palate” or “temporary dentures chew as well as permanent ones” also do not match the facts, so separating symptoms from causes and having them assessed at a clinic is needed [2].
