Below Her Mouth Image

Canker sores, also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums. Unlike cold sores, canker sores don't occur on the surface of your lips and they aren't contagious. They can be painful, however, and can make eating and talking difficult.

The oral tongue is the part you see when you poke your tongue out at someone. This is the front two thirds of your tongue. Cancers that develop in this part of the tongue come under a group of cancers called mouth (oral) cancer.

The most common type of tongue cancer is squamous cell carcinoma (SCC). Squamous cells are the flat, skin like cells that cover the lining of the mouth, nose, larynx, thyroid and throat. Squamous cell carcinoma is the name for a cancer that starts in these cells.

Like X-rays taken in other parts of your body, dental X-rays use electromagnetic radiation to capture images of your mouth. The radiation beam passes through your soft tissues and creates images of your teeth and bones.

Occlusal X-rays help your dentist detect any issues in the floor or roof of your mouth. These images are helpful when diagnosing fractured or impacted teeth or evaluating the roots of your front teeth. Occlusal images can also help identify cysts, abscesses and jaw fractures. Pediatric dentists may use occlusal X-rays to evaluate developing teeth.

Wearing well-fitting face masks helps prevent the spread of COVID-19. For masks to work, they have to be worn properly. Choose a mask with two or more layers that completely covers your mouth and nose and fits snugly against the sides of your face, leaving no gaps. Do not wear a mask that is too loose on the sides. Do not pull the mask low on your nose, below your nose, or below your mouth or chin. Do not leave your chin or your mouth exposed or dangle the mask from one ear. Do not wear the mask in any other way that does not entirely cover your mouth and nose. Wash your hands before and after wearing the mask and use only the loops of the mask to put it on and take it off. Do not touch the front of the mask while wearing it. If you use a cloth mask, wash it and dry it daily and keep it in a clean, dry place.

The division of the GI tract into upper and lower is a matter of some confusion and debate. On embryologic grounds, the GI tract should be divided into upper (mouth to major papilla in the duodenum), middle (duodenal papilla to mid-transverse colon), and lower (mid-transverse colon to anus), according to the derivation of these 3 areas from the foregut, midgut, and hindgut, respectively.

Nevertheless, the GI tract is conventionally divided into upper (mouth to ileum) and lower (cecum to anus). From the point of view of GI bleeding, however, the demarcation between the upper and lower GI tract is the duodenojejunal (DJ) junction (ligament of Treitz); bleeding above the DJ junction is called upper GI bleeding, and that below the DJ junction is called lower GI bleeding.

The mouth (the opening between the upper and lower lips) leads to the oral cavity, which has a vestibule lying between the lips, the cheeks and gums (gingivae), and the teeth. The main oral cavity lies between the hard and soft palate above, the tongue below, and the alveoli and teeth. Salivary gland ducts (parotid, submandibular, and sublingual) open into the oral cavity. The oral cavity leads to the pharynx through the fauces, which contain pharyngeal tonsils (adenoids) and palatine tonsils.

The pharynx extends from the base of the skull above to the cricoid cartilage (at the level of C6) below. It has 3 parts: the nasopharynx (from the base of the skull above to the soft palate below), the oropharynx (from the soft palate above to the hyoid bone below), and the laryngopharynx (from the hyoid bone above to the cricoid cartilage below). The nasal cavity, oral cavity, and larynx open into the nasopharynx, oropharynx, and laryngopharynx, respectively. The laryngopharynx also has a piriform fossa on either side.

The thoracic esophagus enters the abdomen via the esophageal hiatus in the diaphragm at the level of T10 (see the image below) and has a small (2-3 cm) intra-abdominal length. The esophagogastric junction (cardia), therefore, lies in the abdomen below the diaphragm to the left of the midline at the level of T11.

The salivary glands make saliva and empty it into your mouth through openings called ducts. Saliva helps with swallowing and chewing. It can also help prevent infections from developing in your mouth or throat.

The parotid glands are the largest salivary glands. They are located just in front of the ears. The saliva produced in these glands is secreted into the mouth from a duct near your upper second molar.

There are hundreds of minor salivary glands throughout the mouth and the aerodigestive tract. Unlike the major salivary glands, these glands are too small to be seen without a microscope. Most are found in the lining of the lips, the tongue, and the roof of the mouth, as well as inside the cheeks, nose, sinuses, and larynx (voice box).

Nicotinic StomatitisIn nicotinic stomatitis, the hard palate (roof of the mouth) appears white instead of pink, and numerous, small raised areas with red centers are found throughout the palate (see Left). These red areas are irritated minor salivary glands whose duct openings are inflamed in response to the heat from tobacco products. This lesion is most commonly seen in older male tobacco users who smoke pipes but it also can be found in cigar and cigarette smokers.

There is an increased risk for cancer of the tonsils, posterior mouth, and lungs in individuals who develop nicotinic stomatitis from their tobacco use. However, if the individual stops their tobacco use, the appearance of hard palate typically returns to normal within a few weeks.

Gingival Recession and Tooth AbrasionIn addition to the development of changes to the oral tissues, the use of smokeless tobacco can damage both the gum tissue and the teeth in the area where it is held in the mouth. Smokeless tobacco can result in localized gum recession and the exposed teeth often develop dental decay due the sweetener in smokeless tobacco. Unfortunately, stopping the tobacco use does not reverse the gum problem or tooth decay.

Black Hairy TongueHairy tongue (please see PATIENT INFORMATION SHEET: Hairy Tongue) results from either an overgrowth of the normal tongue papillae or a decrease in the rate that the papillae are removed. With tobacco use the overgrown papillae can trap pigment from the tobacco and take on a black appearance. This condition has no symptoms; however, it may be a concern due to the appearance and the frequent unpleasant mouth odor from the trapping of particles in the tongue.

Oral CancerUse of tobacco products is clearly linked to development of oral cancer (see Below). Oral cancers are found primarily in the floor of the mouth (under the tongue), the sides and underside of the tongue, and the soft palate (the back part of the roof of the mouth). The topic of oral cancer in discussed in a separate Patient Information sheet. The most important key to surviving oral cancer is early detection. The importance of your dentist performing a thorough soft tissue examination cannot be overemphasized. The tissue changes in early cancer can be subtle and it is essential for your dentist to perform a through soft tissue examination to detect cancer at an early stage. He or she may want to take a sample of these tissues (biopsy) for diagnosis, or refer you for this procedure. This is the only way to make a diagnosis of oral cancer, and biopsy can also help in determining your long-term outlook.

Identification: Lionfish have distinctive brown or maroon, and white stripes or bands covering the head and body. They have fleshy tentacles above their eyes and below the mouth; fan-like pectoral fins; long, separated dorsal spines; 13 dorsal spines; 10-11 dorsal soft rays; 3 anal spines; and 6-7 anal soft rays. An adult lionfish can grow as large as 18 inches, while juveniles may be as small as 1 inch or less. Lionfish have cycloid scales (fish scales that are oval or elliptical in shape with a smooth edge).

Also called fever blisters, you don't get cold sores from fevers or colds but they can be triggered by them. The virus that causes cold sores is usually passed via a kiss, shared utensils, or other close contact. Over-the-counter creams and ointments may help discomfort and speed healing. Frequent sores may require a prescription. Cold sores are a top mouth problem. Other problems include canker sores, TMJ, bad breath, and mouth cancer. 041b061a72
