The Common Materials for Repairing Caries - Pmma

The symptoms of dental caries

Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.

Cavities and tooth decay are among the world's most common health problems. They're especially common in children, teenagers and older adults. But anyone who has teeth can get cavities, including infants.

If cavities aren't treated, they get larger and affect deeper layers of your teeth. They can lead to a severe toothache, infection and tooth loss. Regular dental visits and good brushing and flossing habits are your best protection against cavities and tooth decay.


Symptoms caused by dental caries

The signs and symptoms of cavities vary, depending on their extent and location. When a cavity is just beginning, you may not have any symptoms at all. As the decay gets larger, it may cause signs and symptoms such as:

Toothache, spontaneous pain or pain that occurs without any apparent cause.

Tooth sensitivity.

Mild to sharp pain when eating or drinking something sweet, hot or cold.

Visible holes or pits in your teeth

Brown, black or white staining on any surface of a tooth.

Pain when you bitefood or anything else.


Discrimination of shallow caries, medium caries and deep caries

shallow caries, medium caries and deep caries are all different stages in the progression of caries. Caries is caused by, in some cases, bacterial damage to the tooth tissue, causing the hard tissue of the tooth to be damaged. The three levels of shallow, medium and deep respectively indicate the shallow, medium and deep formation of the cavity. The deeper it is, the closer it is to the pulp tissue.Somedetails as follows:

1. In the case of shallow caries, the caries only occurs in the enamel, and the patient has no feeling of heat and cold. If the caries occurs at the root of the tooth, the caries occurs in the cementum, and there may be mild discomfort of heat and cold.

2. When the caries are in the middle, the caries has progressed to the dentin inside the enamel. If the dentin is damaged, transient discomfort may occur. Some patients with middle caries have no subjective symptoms.

3. Deep caries is already very deep and occurs in the deep layers of dentin. The stimulation of cold and heat is more obvious. For example, if you drink a mouthful of cold water and have a toothache, it indicates that the tooth may have deep caries. That is, the patient does not feel the toothache, but the doctor found out a lot of faults after examination, but the patient himself did not realize that oral examination should be carried out frequently to eliminate the caries in the state ofshallowcaries.


Using Bloomden Pmma material to repair caries

PMMA material (polymethyl methacrylate) is a synthetic acrylic without inorganic fillers.

We generally use Pmma materials to repair caries. What are the advantages of choosing Bloomden PMMA?

The main characteristics of PMMA are the following:

1.Outstanding optical properties. bloomden PMMA 98

2.Translucency and gloss finish.

3.Rigidity and dimensional stability.

4.Hardness and resistance to scratching.

5.Excellent resistance to sun rays (ultraviolet radiation) and weathering aging.

6.Pmma is cheaper than zirconia materials, so it is a good choice for filling teeth.

But if we have deep caries, then we should consider root canal treatment. Bloomden Pmma is also the best choice for you if there is no high requirement for strength. If you want to choose to repair teeth with a harder material,then consider zirconia material.

What is PMMA used for in dentistry?

A wide range of polymers are commonly used for various applications in prosthodontics. Polymethyl methacrylate (PMMA) is commonly used for prosthetic dental applications, including the fabrication of artificial teeth, denture bases, dentures, obturators, orthodontic retainers, temporary or provisional crowns, and for the repair of dental prostheses. Additional dental applications of PMMA include occlusal splints, printed or milled casts, dies for treatment planning, and the embedding of tooth specimens for research purposes.

What can we do to prevent dental caries?

Good oral and dental hygiene can help you avoid cavities and tooth decay. Here are some tips to help prevent cavities. Ask your dentist which tips are best for you.


Brush with fluoride toothpaste after eating or drinking. Brush your teeth at least twice a day and ideally after every meal, using fluoride-containing toothpaste. To clean between your teeth, floss or use an interdental cleaner.

Rinse your mouth. If your dentist feels you have a high risk of developing cavities, he or she may recommend that you use a mouth rinse with fluoride.

Visit your dentist regularly. Get professional teeth cleanings and regular oral exams, which can help prevent problems or spot them early. Your dentist can recommend a schedule that's best for you.

Avoid frequent snacking and sipping. Whenever you eat or drink beverages other than water, you help your mouth bacteria create acids that can destroy tooth enamel. If you snack or drink throughout the day, your teeth are under constant attack.

Eat tooth-healthy foods. Some foods and beverages are better for your teeth than others. Avoid foods that get stuck in grooves and pits of your teeth for long periods, or brush soon after eating them. However, foods such as fresh fruits and vegetables increase saliva flow, and unsweetened coffee, tea and sugar-free gum help wash away food particles.

Ask about antibacterial treatments. If you're especially vulnerable to tooth decay — for example, because of a medical condition — your dentist may recommend special antibacterial mouth rinses or other treatments to help cut down on harmful bacteria in your mouth.
