Dental Abscess - antibiotics prescribed to treat painful swelling but don't wish to use them

Hello – I would be grateful for any advice with regard to the following

Early last week I noticed a slight tenderness on one tooth which over night turned intense pain – a quick visit to my dentist identified a dental abscess which was treated by a root canal filling – the pain went immediately and all seemed well – unfortunately overnight a distinct swelling appeared on the left side of my face

The lump quite painful to touch and is located slightly to the left of my nose - I revisited the dentist the next day who prescribed penicillin – not keen on using antibiotics , hence the request for advice.

The lump responds well to cold treatment and is worse when heated, pressure is builing and I can now feel a slight eruption on the gum directly below the lump.

No problems with the teeth now – no pain – the only problem is the discomfort from the lump – strange if I bend over it to pick something up it seems to cause a change to the pain which is normally just a dull ache but constant

Gum is now feeling bruised and tender as if it is going to erupt, but this cyclical during the day.

Any suggestions as to a remedy to ease the swelling?

Now a bit about me

52 years old, over weight with raised blood pressure and high cholesterol but working hard on both and exercise in the swimming pool 3 times a week

Currently suffer from psoriasis on scalp and elbows – dry scaly skin but no pus just itchy when hot – but sunshine does it a power of good

I’m a now classed as a bit of a grumpy old devil who speaks his mind a bit to often and does not mine being at the centre of any activity or being on my own as I enjoy my own company just as much as others.

Not keen on public speaking and can get quite nervous when called to do so – but have learned enough tricks to hide it.

Part of a small and very close family and at present without any great worries

Food preferences, like most food (except fish don’t know why), usually enjoy spicy food more, also have a sweet tooth but manage to control that most of the time

I don’t smoke and only drink a few glasses of red wine each week

Only major medical problem in the past was osteomyalitis some 40 years ago

Thanks for your help
