Adjusting to new dentures can be challenging, especially when your mouth feels sore or irritated. If you’re thinking, My new dentures are killing me, you’re not alone. Many people experience some level of discomfort when they first start wearing dentures. Unlike natural teeth, dentures take time to get used to, as they rest on the gums instead of being anchored by roots. The good news is that this pain is usually temporary and can often be managed with the right care and guidance from your dentist.
Why New Dentures Can Cause Pain

Poorly fitting dentures, on the other hand, can rub against the gums and cause sore spots, swelling, and pain. As your jaw and gums change shape over time, dentures may become loose or ill-fitting, leading to discomfort. This is why regular checkups are important to ensure your dentures fit properly and don’t cause unnecessary irritation.
Common Causes of Denture Discomfort
It’s normal to feel some irritation when you first start wearing dentures, but ongoing denture pain could mean something isn’t quite right. Understanding the main reasons behind this discomfort can help you find relief faster and prevent further issues. Whether it’s pressure on your gums, changes in your mouth’s shape, or a buildup of bacteria, identifying the cause is the first step to making your dentures fit and feel better.
Gum irritation and sore spots
Gum irritation is one of the most common reasons new dentures hurt. When dentures press unevenly on your gums, sore spots can develop. These areas may become tender or even inflamed, especially if food particles get trapped underneath.
Poorly fitting dentures
If your dentures don’t fit snugly, they can shift as you talk or chew. This constant movement can cause friction, which may lead to denture sores or swelling. Ill-fitting dentures may also affect how you chew and speak, making daily activities uncomfortable.
Denture adhesive and hygiene issues
Not cleaning your dentures daily can allow bacteria to build up, increasing irritation and the risk of infection. Food particles trapped under your dentures can also cause pain and unpleasant odours. A proper daily cleaning routine helps prevent these problems and keeps your mouth healthy.
What You Can Do When Dentures Hurt
If you’re struggling with denture pain, don’t lose hope. Discomfort when wearing dentures is quite common at first, but there are several ways to ease the irritation and help your mouth adjust. The key is to care for your gums, follow a proper cleaning routine, and visit your dentist for any necessary adjustments. Here are some practical steps to relieve denture pain and prevent further irritation.
Give your mouth time to adjust.
It is normal to feel discomfort during the first few weeks of wearing dentures. Your gums and jaw need time to adapt to the new appliance. If the pain is mild, try sticking to soft foods and taking small bites as you adjust.
Schedule a dental check.
If you experience lasting discomfort, contact your dentist to have your dentures checked. Sometimes, minor adjustments are needed to relieve the irritating pressure points. Never try to adjust your dentures yourself, as this can cause more harm to your gums, affect how your dentures fit, and even change the shape of your mouth.
Keep your dentures clean.
Clean your dentures each day to get rid of bacteria and trapped food particles. This helps prevent gum irritation and denture sores. Use gentle cleaning methods and avoid hot water, which can alter the shape of your dentures.
Use denture adhesive properly.
Denture adhesive can help improve stability and reduce movement, but using too much can cause buildup and discomfort. Your dentist can recommend the correct amount and type for your situation.
When to Seek Professional Help
If your dentures hurt for more than a few weeks or the pain worsens over time, it’s important to see your dentist. Persistent discomfort may indicate that your dentures need refitting or that an underlying problem is irritating. In some cases, implants may be suggested to improve denture stability and comfort.
