Can You Wear Dentures During Surgery?

Removable dentures are almost always taken out before general anesthesia, though the exact timing varies by hospital and anesthesiologist. The concern is straightforward: a loose prosthesis in your mouth while you are unconscious creates a risk of it sliding into your throat or airway. That said, the picture is more nuanced than a blanket “no.” Some anesthesiologists prefer to leave dentures in place during the early stages of anesthesia to help with mask ventilation, only removing them right before a breathing tube is inserted. For procedures done under local anesthesia or light sedation where you stay awake, dentures can often stay in. The final call belongs to the anesthesiologist managing your airway.

Why Dentures Are Removed Before General Anesthesia

When you go under general anesthesia, you lose the muscle control and reflexes that normally keep objects from slipping down your throat. A removable denture, whether full or partial, becomes a foreign body in a relaxed, unprotected airway. Case reports document dentures being accidentally swallowed or aspirated during the induction phase of anesthesia, sometimes before the breathing tube is even placed. A fifteen-year review of swallowed and aspirated dentures found that six of the documented incidents occurred during general anesthesia, alongside cases during eating, sleeping, seizures, and trauma.¹ Those numbers may sound small, but a denture lodged in the esophagus or trachea can require emergency endoscopy or surgery to retrieve, turning a routine procedure into a serious complication.

Partial dentures deserve extra caution. Because they clip onto remaining natural teeth with metal clasps, they can dislodge during airway manipulation without anyone noticing immediately. One case report describes a partial denture that was swallowed spontaneously during mask ventilation before intubation, with the patient developing swallowing difficulty afterward that was traced to the impacted prosthesis.² Another case documented a partial denture discovered as the cause of post-intubation dysphagia.³ The risk is higher in elderly patients and those with poorly fitting prostheses, and the growing proportion of older adults with partial dentures has made this a more pressing concern for anesthesia teams.

The Ventilation Paradox

Here is where things get interesting, and where the simple “take them out” rule runs into a real clinical tradeoff. Before a breathing tube is placed, the anesthesiologist ventilates you using a bag and mask pressed against your face. If you have no teeth and no dentures in place, your cheeks and lips collapse inward, making it hard to get a good seal with the mask. Missing teeth also shrink the space inside your mouth, and the tongue can fall backward more easily, partially blocking the airway.

Leaving dentures in during this mask ventilation phase actually helps. A study comparing dentures-in versus dentures-out during bag-mask ventilation at anesthesia induction found that successful ventilation was achieved in roughly 73% of patients who kept their dentures in, compared with only about 49% of those whose dentures were already removed.⁴ That is a substantial difference. Missing teeth have been identified as a significant risk factor for difficult bag-mask ventilation in broader research on airway predictors.⁵

So some anesthesiologists adopt a staged approach: they leave your dentures in during the initial ventilation phase, then remove them just before placing the breathing tube or laryngeal mask airway. This captures the ventilation benefit while avoiding the aspiration risk during intubation. Others prefer to remove dentures on the ward before you arrive in the operating room and use alternative techniques, such as packing gauze in the cheeks, to improve the mask seal. The same ventilation study noted that oral gauze packing was considered a rational alternative because dentures themselves can push the tongue toward the palate and create obstruction in some patients.⁵ In practice, both strategies are used, and neither is universally standardized.

When You Can Likely Keep Them In

Not every surgery involves general anesthesia. If your procedure is being done under local anesthesia (your dentist numbing a specific area, for instance, or a dermatologist removing a lesion), you are awake and in control of your swallowing and airway reflexes the entire time. Dentures are not a safety hazard in these situations, and there is no medical reason to remove them.

Sedation falls somewhere in between. Light or “conscious” sedation, the kind used for colonoscopies or minor outpatient procedures, generally lets you breathe on your own and maintain basic reflexes. Many facilities allow dentures to stay in during conscious sedation, though individual policies differ. Deeper sedation that approaches general anesthesia typically triggers the same denture-removal protocols. If you are unsure what level of sedation your procedure requires, ask during your pre-operative appointment. The anesthesiologist or nurse anesthetist can tell you whether removal will be necessary.

Regional anesthesia, such as a spinal block for a knee replacement or an epidural for a cesarean section, also does not directly affect your airway. You are usually awake or lightly sedated, and your dentures can stay in place. The caveat is that if there is any chance the procedure could convert to general anesthesia (say, if a complication arises), the team may ask you to remove them as a precaution.

Fixed Implants Are a Different Story

If your “dentures” are actually implant-supported prostheses screwed or cemented onto posts in your jawbone, they are not going anywhere during surgery. These function like natural teeth for airway-management purposes: they cannot be dislodged by mask ventilation or swallowed during intubation. You do not need to remove them, and in most cases you physically cannot without dental tools.

What your anesthesia team does need to know is that they are there. A pre-anesthetic dental assessment should identify any prosthetics in your mouth, whether removable dentures, fixed bridges, crowns, or implant-retained devices. One quality-improvement program designed a standardized electronic dental chart specifically to document dental prosthetics, fixed and removable dentures, and the degree of any loose natural teeth before surgery.⁶ This documentation helps the team plan their airway approach and reduces the risk of damage to expensive dental work during laryngoscopy.

The Emotional Side of Handing Over Your Teeth

For many denture wearers, being asked to remove their teeth in front of strangers ranks among the most stressful parts of the surgical experience. A study of pre-operative distress found that denture removal was one of the most common contributors to patients’ anxiety before surgery, alongside waiting for transfer to the operating room and being told they could not drink.⁷ People who have worn dentures for years sometimes feel exposed or humiliated without them. Sitting on a ward for hours, speaking to nurses and porters, and being wheeled through hospital corridors without your teeth is not a trivial concern. It affects dignity and willingness to communicate.

Research into patient preferences found that nurses should allow patients a choice about what happens to their dentures before going to the operating room, though the anesthesiologist retains the final decision on safety grounds.⁸ In practice, a growing number of hospitals now let patients keep dentures in until they arrive in the anesthesia room, removing them at the last possible moment and returning them as soon as the patient wakes up. One before-and-after study in hip fracture patients used a protocol where patients kept their dentures, glasses, and hearing aids until anesthesia induction and received them back as soon as they regained consciousness, with a transport case provided for hygienic storage during the procedure itself.⁹ That approach minimizes the time patients spend without their prosthesis while keeping the airway safe during the critical window.

How Dentures Get Lost or Damaged in Hospitals

Airway safety is one risk; losing your dentures entirely is another. Hospitals have a persistent problem with dentures going missing during admissions. They get wrapped in tissues and thrown away with meal trays, placed in unlabeled cups that get discarded, or lost during transfers between wards. A quality-improvement study at one acute hospital in England found that an average of 25 dentures were lost per year, yet only about four compensation claims were filed annually, meaning most patients simply absorbed the cost.¹⁰ The study estimated that if every lost denture were reimbursed at the average replacement cost, a single hospital trust would face bills of over £14,000 per year. Scaled across all acute trusts in England, the annual figure could reach about £1.9 million.

A broader investigation across hospitals in southern England confirmed the pattern, finding that seven trusts collectively reimbursed over £357,000 for denture losses over six years, with the highest single reimbursement reaching £2,200.¹¹ These are not small numbers. A well-fitting set of dentures represents a significant personal investment, and replacing them involves multiple dental appointments over weeks or months.

You can reduce the risk by bringing a labeled denture case with you to the hospital. Write your name on the case with permanent marker or use a label. When your dentures come out, put them directly in the case yourself if you are able, and make sure whoever is holding them knows what is inside. Some hospitals now provide labeled containers as part of their admission kits, but not all do, and relying on a tissue wrapped around your teeth on a bedside table is exactly how they get thrown away.

Dental Damage During Intubation

Even when your dentures are safely removed, your remaining natural teeth and any fixed dental work face some risk during intubation. The laryngoscope, the instrument used to guide the breathing tube into your windpipe, presses against the upper front teeth as leverage. Chipped, cracked, or knocked-out teeth are among the most common complications of general anesthesia, though still relatively rare. Loose or weakened teeth, prominent crowns, and bridgework are especially vulnerable.

This is why the pre-anesthetic dental assessment matters. When the anesthesia team knows about fragile dental work ahead of time, they can use protective mouth guards, choose a video laryngoscope that requires less force, or simply be more careful during the procedure. A quality-improvement program that introduced standardized dental charting into its pre-anesthetic evaluation was designed specifically to reduce these injuries.⁶ If you have crowns, veneers, bridges, or any loose teeth, mention them explicitly during your pre-operative visit. Do not assume the team will notice on their own.

There is also a legal dimension. A review of 21 years of liability lawsuits related to dental injuries during anesthesia in France found that among the cases that went to court, the most common reason for a ruling against the medical team was not carelessness during the procedure itself but failure to inform the patient about the risk beforehand. Lack of information led to conviction in a higher proportion of cases than technical negligence did.¹² The use of a protective device was noted as a factor that could reduce the damages awarded in compensation.¹³ This means you have a right to be told about the risk and to discuss precautions. If the conversation does not come up, raise it yourself.

What to Tell Your Surgical Team

Your pre-operative checklist should include a clear conversation about your dental situation. Here is what is worth communicating:

• Type of prosthesis: Full removable dentures, partial removable dentures with clasps, implant-retained overdentures (removable but anchored to implants), or fully fixed implant-supported prostheses. Each carries different implications for airway management.
• Fit quality: Dentures that are loose or ill-fitting are more likely to dislodge during mask ventilation. If yours are old and do not grip well, say so.
• Remaining natural teeth: If you still have natural teeth alongside partial dentures, tell the team about any that are loose, capped, or crowned.
• Removal preferences: If the idea of being without your teeth on the ward causes you significant distress, say that plainly. Many teams will accommodate keeping them in longer and returning them sooner.

Anesthesia teams deal with this routinely, and the conversation does not need to be awkward. The more information they have about your mouth, the better they can plan. This is especially true for emergency surgery, where there is less time for a thorough dental assessment and the risk of denture-related complications rises.

Dentures and Post-Operative Recovery

Getting your dentures back promptly after surgery matters for more than comfort. Dentures affect your ability to eat, drink, and speak clearly during recovery. Older adults in particular may become confused or agitated when they cannot see, hear, or communicate properly after waking from anesthesia. The hip-fracture study that tested early return of sensory aids, including dentures, was motivated partly by research linking sensory deprivation to post-operative delirium in elderly patients.⁹ Having your teeth back lets you eat solid food sooner, speak to nurses about your pain levels, and feel like yourself at a time when everything else feels unfamiliar.

If you are having outpatient surgery and going home the same day, your dentures will typically be returned in the recovery room once you are alert. For inpatient stays, make sure the nursing staff on your ward knows where your dentures are stored and that you want them back as soon as medically appropriate. The labeled case you brought becomes your best insurance that they make it back to you intact and on time.
