Special Offers. You can't see them, feel them or taste them, but your mouth is home to entire colonies of microorganisms. Others, known as probiotics, are beneficial bacteria that aid in the digestion of foods. Other bacteria actually protect our teeth and gums. There are some bacteria, however, that we'd rather do without, since they cause tooth decay and gum disease. It lives in your mouth and feeds on the sugars and starches that you eat.

That alone wouldn't be so bad, but as a by-product of its ravenous appetite, it produces enamel-eroding acids, which make streptococcus mutans the main cause of tooth decay in humans.

Porphyromonas gingivalis is usually not present in a healthy mouth, but when it does appear, it has been strongly linked to periodontitis. Periodontitis is a serious and progressive disease that effects the tissues and the alveolar bone that support the teeth.

It is not a disease to be taken lightly. It can cause significant dental pain, and can eventually lead to tooth loss. Once you've got a strain of oral bacteria, you're not likely to rid yourself of it.

The good news is that you can manage and control the bacteria in your mouth with good oral care. Brushing after meals and flossing at least once per day can remove the source of food for harmful bacteria, which can keep them from reproducing in your mouth. Antibacterial mouthwash can also be used to keep your oral flora from taking over. Your diet also plays a role in managing bacteria. Avoiding sugary and starchy foods, especially when you don't have access to a toothbrush, helps constrain bacterial growth.

Also, eating foods that are known to promote healthy bacteria will help you keep your teeth and mouth healthy for a lifetime.

Always seek the advice of your dentist or other qualified healthcare provider with any questions you may have regarding a medical condition or treatment.

The key players are incisors, canines, premolars, molars, crowns, gum line, root, enamel, dentin and pulp. Canines — sometimes called cuspids, these teeth are shaped like points cusps and are used for tearing and grasping food.

Premolars — these teeth have two pointed cusps on their biting surface and are sometimes referred to as bicuspids. The premolars are for crushing and tearing food. Molars — used for grinding and chewing food, these teeth have several cusps on the biting surface to help in this process. It can be damaged by decay if teeth are not cared for properly.

Dentin — this is the layer of the tooth under the enamel. If decay makes it through the enamel, it next attacks the dentin — where millions of tiny tubes lead directly to the dental pulp. Pulp — this is the soft tissue found in the center of all teeth, where the nerve tissue and blood vessels are located.

If tooth decay reaches the pulp, you usually feel pain and may require a root canal procedure. All Rights Reserved. You are viewing the US English site. Search Search. Oral Care Center.

Types of Bacteria in the Mouth, What They Do | Colgate® Oral Care

Oral microbiology is the study of the microorganisms microbiota of the oral cavity and their interactions between oral microorganisms or with the host. It provides a source of water and nutrients, as well as a moderate temperature. Anaerobic bacteria in the oral cavity include: Actinomyces , Arachnia , Bacteroides , Bifidobacterium , Eubacterium , Fusobacterium , Lactobacillus , Leptotrichia , Peptococcus , Peptostreptococcus , Propionibacterium , Selenomonas , Treponema , and Veillonella.

Bacterial adhesion is particularly important for oral bacteria. Oral bacteria have evolved mechanisms to sense their environment and evade or modify the host. Bacteria occupy the ecological niche provided by both the tooth surface and gingival epithelium. However, a highly efficient innate host defense system constantly monitors the bacterial colonization and prevents bacterial invasion of local tissues.

A dynamic equilibrium exists between dental plaque bacteria and the innate host defense system. The oral microbiome, mainly comprising bacteria which have developed resistance to the human immune system, has been known to impact the host for its own benefit, as seen with dental cavities. The environment present in the human mouth allows the growth of characteristic microorganisms found there. With the appearance of the teeth during the first year colonization by Streptococcus mutans and Streptococcus sanguinis occurs as these organisms colonise the dental surface and gingiva.

Other strains of streptococci adhere strongly to the gums and cheeks but not to the teeth. The gingival crevice area supporting structures of the teeth provides a habitat for a variety of anaerobic species.

Bacteroides and spirochetes colonize the mouth around puberty. The habitat of the oral microbiome is essentially the surfaces of the inside of the mouth.

Saliva plays a considerable role in influencing the oral microbiome. When kissing, it takes only 10 seconds for no less than 80 million bacteria to be exchanged by the passing of saliva. However, the effect is transitory, as each individual quickly returns to their own equilibrium. Thanks to progress in molecular biology techniques, scientific understanding of oral ecology is improving.

In equilibrium, the bacterial biofilm produced by the fermentation of sugar in the mouth is quickly swept away by the saliva, except for dental plaque. In cases of imbalance in the equilibrium, oral microorganisms grow out of control and cause oral diseases such as tooth decay and periodontal disease. Several studies have also linked poor oral hygiene to infection by pathogenic bacteria. There are many factors of oral health which need to be preserved in order to prevent pathogenesis of the oral microbiome or diseases of the mouth.

Dental plaque is the material that adheres to the teeth and consists of bacterial cells mainly S. Plaque is a biofilm on the surfaces of the teeth. If not taken care of, via brushing or flossing, the plaque can turn into tartar its hardened form and lead to gingivitis or periodontal disease. In the case of dental cavities , proteins involved in colonization of teeth by Streptococcus mutans can produce antibodies that inhibit the cariogenic process which can be used to create vaccines.

Maintaining a balanced oral microflora is important for total wellness. The best way to maintain this environment is with proper oral hygiene. Insufficient brushing and flossing can lead to gum and tooth disease , and eventually tooth loss. To prevent any possible side effects from poor oral hygiene, it is important to brush and floss every day, schedule regular cleanings, eat a healthy diet and use a recently-replaced toothbrush.

The oral environment temperature, humidity, pH, nutrients, etc. From youth to old age, the entire mouth interacts with and affects the oral microbiome. There, mucous is charged with their removal. Pathogenic oral microflora have been linked to the production of factors which favor autoimmune diseases such as psoriasis and arthritis , as well as cancers of the colon , lungs and breasts.

Another method of communication involves cell—cell signalling molecules, which are of two classes: those used for intra-species and those used for inter-species signalling. An example of intra-species communication is quorum sensing. Oral bacteria have been shown to produce small peptides, such as competence stimulating peptides , which can help promote single-species biofilm formation. A common form of inter-species signalling is mediated by 4, 5-dihydroxy-2, 3-pentanedione DPD , also known as autoinducer-2 Al From Wikipedia, the free encyclopedia.

It was once believed that gastric acid could kill microbes entering the stomach and that the unique ecological environment of the stomach was not suitable for microbial colonisation or infection.

However, several studies using culture-independent methods confirmed that large numbers of acid-resistant bacteria belonging to eight phyla and up to species exist in the stomach, such as Streptococcus sp.
