Thanks for your question regarding your 7 year old Border Collie boy who has a raised area of gum next to his lower left incisor
If he is 7 and hasn't yet had a Veterinary descale and polish, then yes - I would definitley recommend that he has this done
It is quite likely that he has inflammed gums by most of his teeth, particularly the back molars given his age and the fact he hasn't yet had any dental cleaning
This inflammed/raised gum you are seeing is likely gingivitis.
Gingivitis is a fancy way of saying 'inflammed gum'
The gum is likely inflammed due to plaque and tartar getting undertneah the gumline
If left without any Veterinary intervention or dental cleaning, periodontal disease will develop in which the teeth can become loose and he could potentially have to have one or two extracted!
Dental procedures are common in canine and feilne veterinary practice and this will give your boy a nice fresh start once it is done
The best way to go about this is to have a full dental descale and polish under a full general anesthetic.
While a couple of clinics, including mobile clinics offer conscious teeth cleaning - this is ineffective, unsafe and would be stressful for your boy
So - for your boy, I would recommend: full pre anesthetic bloods to check his liver and kidney function and to ensure he is all ok for a full anesthetic.
If this is fine, then your Vets can place IV fluids and give your boy a full anesthetic.
A full dental exam can then be carried out with your boy asleep and if needed, dental xrays to check the jaw and roots of his teeth to ensure he doesn't need any extra work done other than a routine descale and polish
The descale and polish can then be done and your boy woken up! The whole procedure would typically take less than half an hour
Once he has had the clean up, then ongoing cleaning is the best if he will let you do this
There are doggy toothbrushes and toothpastes available for this.
If he won't let you clean them, then dental biscuits are a good way to help minimize plaque and tartar build up
While your boy is asleep, your Vet will also carefully check the oral cavity and in particular the raised area of gum.
If this isn't found to be gingivitis, then your Vet can take a biopsy to ensure it isn't anything nasty.
I hope all of the above makes sense?
