How Often Do Dentures Need to Be Relined?

Dentures are a great way to replace missing teeth, restore the ability to chew, and smile confidently again — but they don’t last forever. Like everything, dentures need maintenance to keep them comfortable and functional. 

Fortunately, Apex Denture Studio in Yakima, Washington, can make your dentures look and feel like new with periodic denture relines. Our expert denturist, Dr. Jason Alsbury, knows the ins and outs of denture relining and can make precise adjustments that make all the difference. 

Here, he explains when and why denture relining is necessary and what can happen if you skip it.

Denture relining 101

When you first get your dentures, they fit the unique contours of your mouth perfectly. Over time, however, the shape of your gums and jawbone can change, affecting how your dentures fit. 

That's where denture relining comes in. 

During denture relining, Dr. Alsbury adds or removes material on the base of your dentures to ensure a snug fit that feels and functions like new.

Signs you need a denture reline

Your dentures don’t come with a notification system to let you know it’s time for a reline, but your mouth will tell you. Here’s what to look for:

Discomfort or soreness

All new dentures take a while to get used to, but once you do, they should feel comfortable and natural. If they suddenly start causing soreness or discomfort, you may be ready for a reline. 

Dentures that no longer fit snugly rub against your gums, causing irritation and even sores, making it tough to eat and speak normally.

Slipping or moving

If your dentures are slipping or moving around in your mouth, it’s a clear sign that they no longer fit properly and are due for a reline.

Difficulty chewing

If chewing is a chore, it might be time for a denture reline. Ill-fitting dentures affect your ability to bite and chew, making mealtimes frustrating and potentially leading to nutritional and digestive problems.

The average frequency of denture relines

It’s natural to wonder how often you should plan for a denture reline, but there’s no pat answer. The frequency varies depending on the type of dentures you have and how your oral tissues change over time. However, here are some general guidelines and timelines.

Interim dentures

Interim dentures are placed right after tooth extraction or dental implant. Since gums and bone can change rapidly during the healing process, these dentures typically require relining more frequently — usually within the first few months.

Complete dentures

A good rule of thumb for complete dentures is to have them relined every one to two years. Of course, this can vary depending on changes in your oral health.

Soft vs. hard 

The type of liner used can also affect how often you need a reline. Flexible partial dentures made of a soft, pliable material may require more frequent adjustments than cast partial dentures, which are more durable and long-lasting.

What happens if you don’t get your dentures relined?

Delaying or ignoring the need for a denture reline can lead to several issues:

Discomfort and pain

Putting off your denture reline only increases your pain and suffering. The problem doesn’t resolve on its own — it worsens. 

Oral health problems

Ill-fitting dentures rub against your gums, causing sores, ulcers, fungal or bacterial infections, tissue overgrowth, and even bone loss over time. 

Overall health problems

Dentures that don’t fit well make it difficult to chew your food thoroughly, which can lead to digestive issues and poor nutrition. 

Types of denture relines

Dr. Alsbury determines the best approach to your denture reline, choosing from three main types:

Hard reline

Dr. Alsbury adds durable acrylic to your denture base for a hard reline. This material is long-lasting and provides a stable fit for people who don’t need frequent adjustments.

Soft reline

A soft reline uses a pliable material for added comfort. It’s a good choice if you have sensitive gums or frequent irritation from hard dentures, but you may need to replace soft relines more often.

Temporary reline

A temporary reline uses a softer material and serves as a temporary solution until you’re ready for a more permanent reline. Dr. Alsbury often uses it for interim dentures or during the healing process.
