A monthly mouth and jaw check is a looking exercise, not a handling procedure. The dragon stays comfortable, the mouth stays closed unless the dragon opens it, and your job is to compare what you see with what you saw last month. Most of the value lies in that comparison: a jawline that has changed shape, a corner of the mouth that looks different, or breathing that has altered are findings precisely because earlier checks established the normal picture. Set the same conditions each time, good light and a calm moment after warming, so differences reflect the dragon rather than the setting.
Jaw Symmetry and Firmness
Start with the head viewed from the front and from above. The upper and lower jaw should meet evenly along their length, with neither side sitting proud, dropped, or shifted. Watch the dragon close the mouth after a yawn or a feed and note whether the seal looks straight. Firmness is judged gently and externally: the jaw of a healthy dragon feels solid along its length, and any impression of softness, flexibility, or a rubbery quality is a finding to raise with a vet, framed as a possibility for the vet to investigate rather than a conclusion drawn at home. The same applies to a jaw that has become visibly misaligned since the previous check. Record the observation with a date and, if the dragon tolerates it, a clear photograph from the front, since a series of photographs shows drift that single glances miss.
Mouth Corners, Colour, and Shed
Move next to the mouth corners and the visible lip line. Look for sores, crusting, swelling, or patches of discolouration along the margins, and compare left with right, because early changes are often one-sided. Retained shed is a regular finding around the mouth: thin, dull remnants can cling at the corners and along the jaw after the rest of the body has shed cleanly, and noting where shed persists month after month is useful history. Watch feeding as part of this section, since a dragon that drops food, chews unevenly, or approaches prey and then backs away is showing you mouth information without any handling at all. None of these observations names a condition; together they form the report a vet actually wants, specific, dated, and compared against a baseline.
Breathing With the Mouth Closed
Finish by watching breathing at rest. A settled dragon breathes with the mouth closed, in a quiet rhythm, without persistent gaping, bubbling at the nostrils, or effort visible in the flanks. Occasional mouth opening during basking is ordinary temperature regulation, so judge breathing away from the basking spot, once the dragon is resting in the cooler end. Breathing that is habitually open-mouthed at rest, noisy, or paired with lethargy or reduced appetite belongs in the vet conversation promptly rather than at the next monthly check. Note how long you observed and what the temperatures were, because context helps the vet weigh a breathing observation fairly.
The Husbandry History to Have Ready
When a mouth or jaw observation reaches the vet, the questions that follow are predictable, so keep the answers current. Expect to report the age of the UVB bulb, the calcium and vitamin routine used on feeder insects and greens, enclosure temperatures, and recent appetite or weight change. These are history to report, not adjustments to improvise after a worrying check; changing supplementation on your own before the appointment muddies exactly the picture the vet needs to read. Write the monthly findings down the day they are made, with bulb age and routine noted alongside. Those dated entries live in Pet Passport on KinsLe, giving each vet visit the dragon's full mouth, jaw, and husbandry history in order.
