Denture relining and repair in Dubai — cracks, breaks, soft and hard relines

Key facts

• Most cracks and lost teeth can be repaired
• Keep broken pieces — avoid home glue
• Hard reline for long-term fit; soft reline for tender gums
• Repeated breaks often mean the fit needs correcting
• Non-healing ulcers over ~2 weeks should be examined

Common denture problems

Typical problems include a crack down the middle of an upper denture, a fracture after the denture is dropped, a tooth that comes off, a broken clasp on a partial denture, and a denture that has become loose or causes sore spots. Cracks often begin as a fine line, particularly when the denture flexes because it no longer fits the gums evenly. Looseness usually develops gradually as the bone under the gums shrinks after tooth loss. Sometimes a change in fit is first noticed as food getting underneath, more reliance on adhesive, or ulcers. Addressing small problems early usually prevents a complete break.

Denture repairs

Many breaks in acrylic dentures can be repaired by joining the fragments and processing new acrylic across the fracture line; lost teeth can usually be replaced and broken clasps on partials can often be repaired or replaced. Simple repairs can sometimes be completed quickly, while others need laboratory time, so it is worth calling the clinic early. Keep all broken pieces and bring them with you. Avoid home glue kits: household adhesives can be toxic, distort the fit and make professional repair harder. If a denture breaks repeatedly in the same place, it is usually a sign that the fit or bite needs correcting rather than just another repair.

Soft and hard relines

A reline adds new material to the fitting surface of the denture so that it matches the current shape of your gums. A hard reline uses rigid acrylic and is the standard long-term approach when the denture is otherwise in good condition. A soft reline uses a cushioned, flexible material and may help people with thin, tender gums or sharp bony ridges, but soft liners tend to degrade and need renewing more often. Temporary tissue conditioners are sometimes used for a short period to let inflamed gums recover before a definitive reline, and are common after extractions or with immediate dentures.

When a new denture is better

Relining and repairing are not always the right solution. A new denture may be recommended when the teeth are heavily worn so that the bite has collapsed and the face looks shorter, when the denture has been repaired many times, when the acrylic is porous and stained, when the appearance is no longer acceptable, or when relines no longer give stability. Dentures are often reviewed for replacement after several years, but the timing depends on wear and changes in your mouth. If a new denture is advised, your existing one may be kept as a spare. Implant-retained options can also be discussed if looseness is a recurring problem.

Preventing breakage and when to seek help

Clean dentures over a folded towel or a basin of water so that they do not break if dropped. Store them in water or a cleanser when out of the mouth, away from children and pets. Do not try to adjust or file a denture yourself. Have the fit checked at regular reviews. Seek prompt advice for a sore spot or ulcer that does not heal within about two weeks, as any non-healing mouth ulcer should be examined. Cost depends on the type of repair or reline and the denture, and you receive a clear explanation before work starts. The clinic is open daily from 11:00 (Saturday from 10:00) to 20:00.

Modern dentures are designed for fit, bite and appearance. When a lower denture moves, two or more implants can hold it in place with click-in attachments.
