Amalgam fillings have been widely used in dentistry to repair decayed teeth for many years. Many elements, including copper, tin, mercury, zinc, and silver, are made of dental amalgam.

Unfortunately, they will leak as these fillings get aged and allow a dark blue, purple, or black color to stain the underlying tissues.

Such stains are permanent and are known as tattoos of amalgam. The lining would either need to be fixed or removed to stop other problems if the dentist thinks a leaky lining is a dark spot.

Melanotic macules

People Most Ask Able Questions & The Specialist Doctors Answers about black dot inside cheek

Q1: My husband has a black spot beneath his tongue on the very back. Will that be cancer?

Doctor Answer: Several factors can cause dark spots in your teeth. They vary from mild damage to benign cancers in the blood arteries, including haemangioma, such as a smear of a dental lining spilled through your gums (called an amalgam tattoo).

Few cancer forms can also present as dark spots. E.g., melanomas (skin cancers) appear like dark spots.

While most people still equate melanomas with exposed areas of the face, they can also appear in the mouth and even inside the nose and sinuses (areas that are not exposed to the sun).

Your husband should test this region by a specialist to see whether more examination is required.

Q2. I have a tough pea lump in my cheek around my jaw (near my molars but not in my gums). I will pass it around. I can move it around. It’s typically really little. It swells up when I’m ill, but it doesn’t always hurt. I’m thinking about cancer. Cancer. What sort of physician can I see? What kind of tests am I possibly going to need?

Doctor Answer: Your primary practitioner or an ear, nose, and throat doctor will help you assess the bump.

The region you mention may be within the parotid gland or inside the upper neck’s lymph nodes.

The fact that it swells in the sick means that a lymph node is more probable.  Because lymph nodes are more like filters in your body and support you in battle diseases, they get larger when you’re sick.

Possibly little to think about as long as it goes back to its usual size afterward. There may be several items in the parotid gland, like a benign tumor (non-carcinogenic). One way to diagnose what kind of mass is by slight suction of a needle.

In this process, a tiny needle is placed into the mass, and several cells are removed. The cells will then be tested under a microscope by a pathologist to assess the disease.

Q3.For months now, the back of my neck has troubled me. As I turn my neck, it seems like there’s something on top of my spine. I have been under many pressures lately and have only taken Advil (ibuprofen) about three days a week or, if appropriate, twice a day. Two days ago, I noticed a round red spot near my throat on the back of my mouth. This brought me to some concern because I was smoking sometimes. I quit right now because I noticed it. My throat was sore, and I had it tested for strep, but it got negative. My concern is how does mouth cancer look? May I be interested? I’m so anxious.

Doctor Answer: Stress in our busy environment is a big challenge. There may be a lack of sleep, inadequate diet, and rising signs of tension, along with reduced immunity.

Bacterial, viral, and even fungi that usually reside in our mouth may grow oral lesions during stress cycles. Stress will also reduce the body’s capacity to repair slight injuries on the body’s jaw.

The mixture of these conditions may contribute to sometimes unpleasant and discolored lesions and ulcers. This type contains multiple cold sores and aphtha’s ulcers. In one to two weeks, these lesions should be cured.

Oral washing with dilute alcohol or saltwater should help avoid infection and can improve healing. Your doctor can assess any lesions that linger or bleed after two weeks.

Q4. Do spicy foods induce cancer of the mouth?

Doctor Answer: This is a powerful query I get from several of my patients who want “bam!” “For their bread. I have studied the topic on many occasions.

While several research is carried out on the function of some spices and spicy foods in reflux and esophagus disease, there is very little proof that the average intake of spicy foods can contribute to oral cancer.

The heavy intake of spicy foods is a possible risk factor for many broad population studies. However, there is seldom a single risk factor.

Sometimes these are the same categories of people who still cigarette and drink—known high-risk mouth cancer behaviors.

The natural response is that we don’t know if the link is clear. Part of the dilemma is that what we are talking about, “spicy foods,” cannot be generalized since it may differ considerably from individual to person, culture to culture.

Latest findings have shown that consuming a broad range of foods – including whole grains and green leafy vegetables – and diminishing fatty foods intake will contribute to lower incidences of several forms of cancer. Weight reduction is beneficial in reducing the incidence of cancer.

So the most excellent suggestion I can offer is to hear what your mother said: eat right. Eat multiple plants. Eat some plants. Don’t consume too many. Don’t eat too many.

Get a lot of workouts. And don’t drink. Don’t smoke. Everything in balance — including the sometimes spicy dinner.

Q5. Can X-rays raise the salivary gland cancer risk? If so, can I restrict the number of X-rays that I get in general dental care?

Doctor Answer: High doses of ionizing radiation have demonstrated that certain tumors, including skin, soft tissue (sarcoma), bone, and thyroid, raise the risk.

These results are seen years and decades following initial therapy. Thus, adults who undergo extensive doses of radiation in infancy are more at risk, typically for childhood cancer care, such as lymphoma or leukemia. The relation between radiation exposure and danger is obvious.

Dental X-rays include a comparatively minimal dosage of radiation, but most patients have a low chance of contracting cancer-related to regular dental X-rays. However, if you are interested, you should still recommend that other areas of the body be protected with lead safety during these procedures.
