Sore Spots With New Dentures: What's Normal and When to Call Your Hamilton Denturist

A new denture sits on gum tissue that hasn't carried chewing force before, so a few tender areas early on are part of the fitting process rather than a sign that something has gone wrong. The ones worth a phone call are the ones that keep returning to the same place, spread, or change how you eat.

Gilmour Denture Clinic has been fitting dentures in Hamilton for over 35 years. Tim Gilmour, DD, handles adjustments and soft liners here, and all of that work is done in our on-site lab. Consultations are free and no referral is needed.

Why Do New Dentures Cause Sore Spots?

Pressure lands unevenly at first. The ridge a denture rests on is rarely a perfectly even surface, so a few points take more load than the tissue around them, and those points show up as tender patches.

They tend to be small and specific rather than a general ache across the whole ridge. A denture that’s been worn for years has already been adjusted at those points one by one, which is why a replacement set can feel sharper at the start than the one it’s replacing.

Sore areas don't all come from the same cause. A pressure point sits underneath, where the denture bears down on the ridge. A rubbing spot usually sits along the edge, where the border of the denture meets the tissue that moves in your cheek or under your tongue. Both feel much alike from the outside and each is relieved differently, which is part of what the denturist is working out at the appointment.

What an Adjustment Actually Involves

The denturist locates where the denture is pressing and relieves that exact area. It's a small amount of material taken off the fitting surface, meaning the side that sits against your gums.

Locating the spot is the part that takes care. A sore area is easiest to pinpoint while it's still visible, so a denture that's been worn for a stretch before the appointment gives the denturist something to mark against.

The fitting surface is shaped to your ridge. Material taken off the wrong part of it changes how the whole denture sits rather than easing the one point, which is why adjustments are done at the clinic, and why a denture that arrives unaltered is one we can read accurately.

A new set usually takes more than one visit to settle in. Material comes off a little at a time, because taking more than a spot needs can leave the denture slack where it was holding well.

When to Wait and When to Call

We usually recommend a check-up at least once a year, and sooner than that if the dentures feel loose, if they’re causing sore spots, or if your mouth has changed. Soreness is on that list deliberately, since it’s one of the clearest signals that the fit needs a look.

• A spot that keeps coming back in the same place after an adjustment. That usually means a little more material needs to come off, or it needs to come off slightly to one side of where it did last time.
• Soreness that spreads across a wider area instead of settling.
• Anything that's changing how you eat or speak beyond the first short stretch.
• Movement that wasn't there before. Looseness and soreness often turn up together,
• because a denture that shifts, rubs as it moves.

There's a practical reason not to sit on it. Tissue that's been rubbed for a while swells, and a swollen ridge is a different shape from the one the denture was built for, so the adjustment takes more passes to get right. A fresh sore spot is simply easier to work from.

Immediate Dentures Follow a Different Pattern

Immediate dentures go in the same visit your teeth come out, which means they’re sitting on gums that are still healing. As your mouth heals the fit may change, and adjustments are usually needed for continued comfort. More visits in that early stretch is how the set is designed to work, since the shape underneath is still settling and the denture is being brought along with it.

Where the issue is rubbing across a broader area rather than one pressure point, we also fit permanent soft denture liners, which put a softer material on the fitting surface to reduce abrasion.

Whether that suits your situation is something we go through at the appointment. Once healing has settled, the space between the denture and the ridge can open up enough that relining the fitting surface makes more sense than adjusting it again, and relines are done here the same day.
