Edit the video to be educational. May be 5 or more than 15 minutes but edited. Best to split into Part 1 (history and diagnosis and Part 2 (treatment and outcome)

 The owner just wanted only clipping of the overgrown incisor teeth for the past 3 months at monthly intervals. Yet the guinea pig became thinner and lost weight. He came in Nov 8, 2016. l noted a left jaw abscess or dental abscess. Physical examination, otoscopic examination of the molars showed molar spurs and skull radiography showed lysis of left mandibular jaw bone - causing an abscess on the left jaws. Clipping of overgrown front teeth is much cheaper but the guinea pig suffered a more serious illness now, being emaciated. The owner agreed to X-rays and hospitalisation. This video shows Day 5 of hospitalisation. The molar spurs were trimmed. The abscess is still be flushed daily. Antibiotics, painkillers and SC and oral fluids daily. Ears cleaned. Nails clipped. The guinea pig now is active and pooping a lot. This guinea pig had never been groomed at all.

A 5-year-old guinea pig is emaciated and had stopped eating and pooping. For the past 3 months, around a month, the father and son would bring the pet for cutting short the front teeth. It was inexpensive. The guinea pig had overgrown molar spurs clipped short by Dr Sing Kong Yuen one year ago and had good appetite. Around 6 months later, the front teeth overgrew and so the owners decided on just asking the vet to clip the front teeth every month for the past 3-4 months. The guinea pig would then be able to eat. But in Nov 8, 2016, they consulted Dr Sing as the guinea pig was not eating and was very thin.

Very thin guinea pig. The owner had given him corn and he ate corn almost exclusively. Isoflurane gas anaesthesia by mask was given. The incisors were clipped short. A lower right molar spur is seen and videoed to show the owner.

molar spurs trimmed under gas anaesthesia 

Tues Dec 1, 2015. The guinea pig's front teeth had been clipped. To be thorough, the molars need to be examined. The right lower molar had overgrown to become a molar spur which is videoed for the owner's education. The molar spur is clipped under anaesthesia. The owner is to hand feed the guinea pig by hand and introduce the pellets and hay more than the corn pieces.

5 days of hospitalization and treatment shown. Overgrown incisors trimmed, molar spurs trimmed. Guinea Pig resumes eating as there is no more oral pain and dental malocclusion Jaw abscess will be drained. X-ray of teeth is done.

This 36-minute video has the left jaw abscess footrage!

In December 2015, the guinea pig had overgrown incisors and molar spurs clipped short by Dr Sing Kong Yuen one year ago and had good appetite. No dental X-rays were taken as the owner wanted the least cost. From July - September 2016, the father and son would bring the guinea pig to cut short the overgrown front teeth only as it was an inexpensive procedure compared to more detailed dental X-rays. The guinea pig would eat again. But in Nov 8, 2016, they consulted Dr Sing as the 5-year-old guinea pig was emaciated, anaemic and was not eating. There was a gigantic left jaw abscess. Two treatment options are available. 1. Marsupialisation - opening up a big hole, drain the abscess and stitch the mucosa (inside layer) of the abscess to the skin, creating an open wound. The wound can be flushed daily. 2. Remove the capsule of the encapsulated abscess. This would permit the pus to be drained At Toa Payoh Vets, I incised and drain the abscess. The decayed molar tooth can be extracted when the guinea pig is in better health. The owner has to return for this dental work. In conclusion, three procedures are needed when the guinea pig has overgrown front teeth and is not eating and loses weight. 1. Physical examination for jaw abscess and dental malocclusion 2. Examination of molar spurs using the otoscope. 3. Skull X-rays, using oblique views to see the teeth.

Advices: Proper diet of hay. Not solely corn

This blog does not show the complete situation. But use the script, edit it if you feel it is not good, to save time.  Make it Part 1 and Part 2. So it will not be so boring.

The vet uses a rodent cheek dilator to open the mouth wide for examination
What did he see?  The lower cheek teeth (X) have overgrown excessively long!
Similarly with the upper cheek teeth

Swelling below the jaw - dental abscess. What happened?

X rays showed bone lysis - infection of the bone area  in the back cheek teeth

USE THESE UPDATED IMAGES

It will be very difficult to diagnose properly without
an X-ray

X-rays are necessary for dental diseases. There is lysis (breakdown of the bone due to infection) of
the mandible (lower jaw) as shown by the dark areas in the roots, below the cheek teeth. 

Anatomy - the adult GP has 20 teeth

Gas anaesthesia without injectable sedatives were much less risky for emaciated

guinea pigs. A gas mask Is used and careful monitoring by the 

assistant is required.  

cheek dilator spreads out the cheeks. Molar cutter trims the excessive length of the
premolars and molars

Narrate and explain the uses of each piece of equipment

Molar spurs are the excessive length of the premolars and molars. The molar cutter trims the
molars. Without the sharp spurs, the guinea pig is able to chew his food normally and put on weight
