Is there a reason for dark brown spots appearing at the corner of the mouth?

Many people get these spots due to smoking. Due you smoke?? That could be the answer.

I had this before, it is probaly a minor infection. Buy some listerine mouthwash and use it, it really works, and also deep some cotton in the mouthwash and put it on the red spot for a while.

that might not be what it is, consider your recent activity and look it up on symptoms on yahoo search or something. It could be a zit or something.

I'm sorry to hear about your trouble but when you ask "what is this?", you're asking for a diagnosis.  Only a licensed physician, nurse practitioner or physician assistant who has examined you in person can make a diagnosis.  If anyone here offers one, ignore it.  Your dentist (what's a dental specialist???) says your mouth is fine, your doctor says your mouth is fine.   But if you truly feel that something is wrong, return to your doctor.  You're not the first this has happened to - bumps on palate.  By any chance did you take Doxycyline?

Hi,\n\nIt's difficult to tell exactly without seeing your mouth but 'Blackening' could be caused for a number of reasons.....\n\nFirst thing please try and stop smoking, most of the patients I see with severe gum problems that lead to losing their teeth are smokers, It really badly affects the gums.\n\n The blackening is very likely due to nicotine staining, but can also be a sign that your gums are receeding, as the root surface of teeth when exposed stains a lot more as the root is more porous. Exposed roots are also more prone to decay, although your Dentist should have spotted if this is the case, and are also a sign of gum disease (very common in smokers)\n\n Ideally you should be seeing a Dental Hygienist every 3 months if you smoke, if there is not one at your practice you can ask your dentist to refer you to one at another practice if need be as long as you have a referral letter.\n\nAbrasive pastes like Eucryl and Pearl Drops should not be used regularly as they will roughen and abrade away the enamel and ultimately make the staining worse and your teeth sensitive , same goes for lemon juice, way too acidic, leave a tooth in lemon juice and it dissolves completely eventually!\n\nIf it is just surface staining I advise my patients to use a toothpaste containing Bicarbonate of soda and and electric toothbrush (you can get them as cheap as £12 now) this can work wonders too. \n\nThe only way to  whiten  teeth properly is to have them professionally cleaned by a Dentist or Hygienist and then bleached  by a dentist. \n\nThe stuff sold in the shops does not contain enough peroxide (the active ingredient) to remove anything but a little suface staining.You need to have at least 10% peroxide and this strength is only legally available to dentists in the UK . To do home bleaching supervised by a dentist costs around £350 but gets fantastic results. You wear two bleaching trays for a couple of hours a night for approx 2 wks depending on lightening needed.\n\nYou can also have speed whitening done at the dentist in 1 hour and at around £650, but beware this can make your teeth and gums very sensitive! better to do it gradually over a couple of weeks when you get the same results anyway.\n\nIf the teeth are really badly stained they may need to be crowned or veneered to make a big difference. \n\nMention your concerns about your appearance to the Dentist at your next appointment, that's what they are there for! they may not even be aware of your concern, but should be able to discuss options with you. Good Luck!\n\nHope this helps!

It could be a spider bite.  She should see her doctor since I am not sure what a brown recluse bit looks like.

You should ask your dentist or be refered to an oral dermatologist, especially if you've smoked or chewed tobacco products.  I had bumps under my tongue and luckily it was something they called plica fimbriata, completely harmless. Don't risk your health in case the oral bumps are related to some type of oral cancel, get it checked out.

Black spots?  Are they freckles?  Could they be small broken capillaries?  Sun spots? Are you a sun goddess?  What do they look like?  Are they liver spots?\n\nAnyway - if they are any of the above... this product takes them away = NO KIDDING  It's called the "sleeping peel liver spot remover"... you put it on and leave it there.  After it dries, you peel it away.  The dark spot comes with it, making it less noticible.  I swear by this.  Give it a try, you'll be glad you did.

Search for the cause it could be from nose or sinuses most probably or mouth [teeth and gums] consult ENT Dr. or Dentist .

Have you had it examined by a doctor? Is this something you've had for a long time or did you just notice it? If it's something recent, have it checked right away it could be signs of something more serious. \n\nI would say this about any medical problem.

it's something you ate or just a minor infection of the mouth in italy we call it "afta".\n\nRinse your mouth with a mild mouthwash(avoid listerine is too strong) it will go away in a couple of days...avoid food spicy or hot and ketchup

Regular micro-grade agar is generally clear (if it's made up right), not brown.  The human mouth is incredibly dirty so if nothing grew it is probably too cold.  Needs warmth and maybe a bit of moisture.  Give it a couple of days in a warm place (not in the sun) and SOMETHING should grow!

That sounds normal.  Usually you will see a pinkish/yellowish looking gel-like substance.  This is the clot and granulation tissue forming.   This immature connective tissue will eventually completely fill in and cover the socket with new gum tissue.  Try to keep this area clean and free of food debris!  As long as you are not experiencing any pain, swelling or bleeding, I wouldn't worry!  I hope that this proves helpful!

Kinda sounds like dentinogenesis imperfecta aka opalescnt dentin. The dentin is abnormal as a result of disturbances in the odontoblastic layer during deverlpment. The teeth appear trasclucent or opalescent  and vary in color from gray to bluish-brown. Go see your dentist.
