Amalgam tattoos
The odds are that this spot on your gums is nothing more than a harmless “tattoo,” leftover from a metal amalgam filling. Before composite and ceramic became the materials of choice for tooth fillings, they used to be made up of materials such as mercury, tin, copper, and silver.
Over time, an amalgam filling may sink down into the gums, or even make its way into the lips, cheeks, or tongue. Parts of the filling may also get pushed into other tissues when your dentist is drilling out tooth decay or when he or she is removing an amalgam filling.
Are amalgam tattoos dangerous?
Most of the time, amalgam tattoos are absolutely nothing to worry about. However, you should be aware that amalgam tattoos can look very similar to mucosal melanomas – a sign of a rare but deadly form of cancer.
Mucosal melanomas typically occur in people who have used tobacco for a long time. They usually appear on the palate or in the inner part of the sinus cavity. If you have a mucosal melanoma you may notice pain and swelling in the mouth, and if you wear dentures you may notice that they don’t fit as well as they used to. If you are concerned that your spot may actually be a mucosal melanoma, especially if you use tobacco, you should see your dentist right away. An examination and an x-ray will be able to determine what the spot is.
How Can Your Dentist Identify an Amalgam Tattoo?
A dark spot on your gums may be an amalgam tattoo, but other oral conditions can cause similar discoloration. At Pacific Northwest Smiles, Dr. Darren Greenhalgh can examine the affected area, review your dental history, and recommend X-rays when appropriate to look for embedded metal particles. If the cause remains uncertain, he can discuss whether a biopsy or referral for further evaluation is necessary.
Finding an unusual spot in your mouth can be unsettling, especially when you are unsure what caused it. Clear explanations from your dentist can help you understand the findings and whether further testing is needed. The Dental Marketing Secrets Podcast explores how dental professionals communicate with patients, address concerns, and build trust through thoughtful conversations.
Frequently Asked Questions
Can an amalgam tattoo disappear on its own?
Amalgam tattoos usually do not fade or disappear naturally because metal particles remain embedded in the oral tissue. Most are harmless and do not require removal.
How can a dentist tell if a dark spot is an amalgam tattoo?
A dentist examines the spot’s appearance, location, and dental history. Dental X-rays may reveal metal particles, but a biopsy may be needed if the diagnosis is uncertain.
Should you see a dentist for a black spot on your gums?
Yes. A new or changing dark spot should be examined to rule out other oral conditions, including rare forms of oral cancer. Pacific Northwest Smiles in Mill Creek, WA, can evaluate unusual gum discoloration.
If you have a black, grey, or bluish spot on your gums, it is most likely nothing to worry about. However, if you have any questions about this or other tooth or gum issues, you can always call Pacific Northwest Smiles. Call 425-357-6400 for an appointment today!
