molar burring under sedation, what to expect

updated 18 May 2026

rabbit dental disease is one of the leading reasons Singapore rabbit owners end up at an exotic vet. the problem starts quietly. cheek teeth (molars and premolars) grow continuously, and without enough hay, they drift out of alignment and form sharp spurs. those spurs dig into the tongue and cheek lining with every chew. by the time you notice your rabbit eating less or dropping food, the damage is often already significant. molar burring uses a rotary burr or dental drill to file those spurs down to a safe height; it happens under sedation. in Singapore, most general vet practices lack the sedation equipment and dental tools for rabbit-specific work, so this is done at exotic-specialist clinics. knowing each stage makes the whole experience far less frightening, from the day you call the clinic to the moment your rabbit is back on hay.

step 1: recognizing why your vet recommends burring

your vet will usually recommend burring after a physical exam. a basic mouth check happens while the rabbit is awake, then a brief sedation follows for the full oral exam. cheek teeth sit too far back to assess clearly in a conscious rabbit.

signs that typically prompt a referral include:

  • reduced hay intake or appetite
  • drooling or a persistently wet chin, sometimes called “slobbers”
  • dropping food mid-chew, or chewing only on one side
  • weight loss without an obvious cause
  • discharge from one or both eyes, since elongated tooth roots can press on the tear duct

if your rabbit shows any of these signs, contact a SG exotic vet promptly. do not wait to see if things improve on their own.

step 2: the pre-procedure consult and fasting

unlike cats and dogs, rabbits should not be fasted before sedation. their gut motility depends on continuous food passing through the digestive tract. fasting a rabbit for more than an hour or two before a procedure raises the risk of GI stasis. it can become life-threatening fast.

your vet will advise you to:

  1. keep hay available right up until you leave the house
  2. bring a handful of the hay your rabbit eats at home; familiar smells help during recovery
  3. arrive early so the vet can take pre-sedation weight and temperature
  4. withhold pellets for two to four hours only if your vet specifically instructs it; follow their exact guidance

during the consult, the vet may take skull X-rays. a small number of specialist centres in Singapore also offer CT imaging for small animals. imaging matters because it reveals root elongation and early abscesses that cannot be seen by looking into the mouth. as of 2026, expect to pay SGD 350 to SGD 700 for a full work-up at Singapore exotic clinics. that covers sedation, oral exam, burring, and X-rays; the final figure depends on complexity and how many teeth need work.

step 3: what happens during sedation

the vet will administer a sedation agent. most exotic vets in Singapore use injectable sedation followed by isoflurane gas, maintained through a small mask or endotracheal tube. rabbit airways are delicate, and exotic vets receive specialist training in managing them that general practitioners do not.

once your rabbit is sedated, the vet or vet nurse will:

  1. position the rabbit carefully with the mouth held open using a speculum
  2. use an illuminated scope to view all cheek teeth clearly
  3. apply a rotary burr or dental drill to file down spurs or overgrown surfaces
  4. irrigate the mouth to clear debris and check alignment
  5. examine the incisors (front teeth) and trim or align if needed
  6. note any root damage or loose teeth that may require extraction at a future visit

the procedure typically takes 20 to 45 minutes depending on severity. you will be asked to wait at the clinic or return within a set window.

step 4: the immediate post-op period

your rabbit will wake up in a quiet, warm space at the clinic. this is the most critical phase. rabbits can lose body temperature rapidly after sedation. the vet team will:

  • monitor breathing and heart rate as the anaesthesia wears off
  • keep the rabbit on a warm pad or under a heat lamp
  • watch for signs of respiratory distress, which is rare but requires immediate intervention
  • offer syringe water once the rabbit is alert enough to swallow safely

most rabbits are alert within 30 to 90 minutes after sedation ends. before discharge, the vet will confirm that the rabbit is breathing normally, has adequate muscle tone, and is responding to stimuli. you will likely receive oral pain relief medication to administer at home. follow the dosing instructions exactly.

step 5: home recovery, the first 48 hours

the first 48 hours matter most. your job at home is to support gut motility, keep your rabbit comfortable, and watch for warning signs.

  1. keep the environment cool. Singapore’s ambient temperature of 28 to 32°C is already stressful for rabbits. post-sedation rabbits need AC set to around 18 to 22°C. a room that is too warm slows gut recovery.
  2. offer hay immediately. even if your rabbit is groggy, place hay directly at their nose. the smell alone stimulates gut movement.
  3. syringe-feed Critical Care if your rabbit does not eat within four to six hours. your vet may send you home with Oxbow Critical Care; mix it with water and offer small amounts every two to three hours.
  4. give pain medication on the schedule the vet prescribed. do not skip doses. a rabbit in pain will not eat, and not eating leads to stasis.
  5. keep the space quiet and low-stress. avoid other pets, loud sounds, or children handling the rabbit while it is still recovering.
  6. check the litter tray every few hours. you want to see droppings within six to eight hours of returning home.

step 6: monitoring progress after 48 hours

by day two or three, most rabbits start eating hay on their own and producing regular droppings. some are still slow to return to pellets; that is expected, since the mouth is healing and chewing may still be sore.

contact your vet immediately if any of these appear:

  • no droppings for eight or more hours
  • loud teeth grinding (bruxism), which signals severe pain; this is distinct from the quiet purring of a comfortable rabbit
  • bloated, hard, or asymmetric abdomen
  • laboured breathing or pale or blue-tinged gums
  • swelling under the jaw or discharge from the mouth
  • complete refusal to eat or drink past 12 hours at home

molar burring is not a permanent fix. most rabbits with dental disease need the procedure repeated every three to six months. your vet will advise on timing based on the rate of regrowth at each follow-up visit.

what owners often get wrong

fasting before the procedure. some owners assume rabbits need to fast the way cats and dogs do. this is incorrect. rabbits must keep eating right up to the procedure. always confirm fasting instructions with your vet directly, but do not remove hay unless specifically told to.

expecting one procedure to resolve the problem. dental disease in rabbits is structural and progressive. burring is management, not cure. owners sometimes delay the next appointment because the rabbit seems fine. by the time obvious symptoms return, spurs may have already cut the tongue or cheek lining again.

skipping the oral X-ray. some owners decline imaging to reduce the bill. tooth root problems are invisible to the naked eye. a vet who burs without imaging may miss an abscess forming beneath the surface. root abscesses are among the most painful and difficult conditions in rabbit medicine.

stopping pain medication early. if your vet prescribes an analgesic for three to five days, complete the full course. stopping early because the rabbit “seems fine” increases pain, suppresses appetite, and slows recovery.
