A dental bridge is a fixed dental restoration that replaces one or more missing teeth, consisting of artificial teeth anchored to adjacent natural teeth with crowns. Chewing gum with a dental bridge requires careful consideration because traditional, sticky gum poses a significant mechanical risk to the restoration’s longevity. Gum creates a pulling force that challenges the cement bond holding the bridge in place. Therefore, most dental professionals recommend extreme caution or avoidance of certain gum types to protect the fixed appliance.
The Specific Risks of Chewing Gum
The primary concern with chewing gum is its sticky adhesive quality, which can lead to a failure of the dental cement bond. As you chew, the gum adheres to the bridge and exerts a continuous, repetitive traction force. This pulling action can be stronger than the dental cement, especially if the bond has already been compromised by wear, age, or underlying decay. This mechanical stress can loosen the bridge entirely or weaken the connection to the supporting teeth over time.
If the bridge becomes dislodged, the underlying natural teeth, known as abutments, are exposed and immediately vulnerable. These abutment teeth were prepared to receive the bridge crowns, and without the protective covering of the restoration, they are susceptible to rapid decay or further injury. Sticky substances like gum can also trap food particles and sugar underneath the restoration. This fosters bacteria growth and decay around the abutment teeth, further compromising the bridge’s support.
Safer Chewing Options and Habits
For individuals who still wish to chew gum, certain choices and habits can significantly reduce the risk of damage. The best alternatives are non-stick, sugar-free gums, particularly those sweetened with xylitol. Xylitol is a sugar alcohol that inhibits bacteria growth and helps neutralize plaque acids. This type of gum is less likely to adhere strongly to the bridge material, minimizing the pulling force that compromises the cement.
When chewing any gum, modify your technique to protect the bridge. Avoid aggressive or prolonged chewing sessions, which increase the strain on the restoration. If the bridge is located only on one side of your mouth, chew predominantly on the opposite side to reduce direct mechanical pressure. Maintaining these mindful habits helps extend the lifespan of the restoration while allowing for occasional gum use.
Immediate Steps If a Bridge Becomes Loose
A loose or dislodged dental bridge is considered a dental emergency because the unprotected abutment teeth can quickly suffer damage. If this occurs, remain calm and carefully retrieve the bridge, rinsing it gently with water. It is important to save the restoration and place it in a clean container, as the dentist may be able to re-cement the existing bridge. Never attempt to force the bridge back into place or use household adhesives to fix it, as this can cause further injury to the gums or damage the restoration.
The most important action is to contact your dentist immediately to schedule an emergency appointment. While waiting for the visit, you should avoid chewing on the side of your mouth where the bridge was located and stick to a soft diet. Prompt professional assessment and re-cementation are necessary to prevent decay and protect the supporting natural teeth that anchor the bridge. If the bridge itself is intact and the abutment teeth are healthy, the dentist can clean and reattach the restoration using fresh dental cement.
