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.

Citlivost zubů.

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.


Rozlišení mělkých kazů, středních kazů a hlubokých kazů

mělký kaz, střední kaz a hluboký kaz jsou různá stádia progrese kazu. Zubní kaz je způsoben v některých případech bakteriálním poškozením zubní tkáně, což způsobuje poškození tvrdé tkáně zubu. Tři úrovně mělké, střední a hluboké označují mělké, střední a hluboké vytvoření dutiny. Čím hlouběji je, tím blíže je k dřeňové tkáni.Někteřípodrobnosti takto:

1. V případě mělkého kazu se kaz vyskytuje pouze ve sklovině a pacient nemá pocit tepla a chladu. IPokud se kaz vyskytuje u kořene zubu, kaz se vyskytuje v cementu a může dojít k mírnému nepohodlí z tepla a chladu.

2. Když je kaz uprostřed, kaz postoupil do dentinu uvnitř skloviny. Pokud je dentin poškozen, může dojít k přechodnému nepohodlí. Někteří pacienti se středním kazem nemají žádné subjektivní příznaky.

3. Hluboký kaz je již velmi hluboký a vyskytuje se v hlubokých vrstvách dentinu. Stimulace chladem a teplem je zjevnější. Pokud například vypijete doušek studené vody a bolí vás zub, znamená to, že zub může mít hluboký kaz. To znamená, že pacient necítí bolest zubů, ale lékař po prohlídce zjistil spoustu závad, ale sám pacient si neuvědomil, že je třeba často provádět ústní vyšetření, aby se odstranil kaz ve stavumělkýkaz.


Using Bloomden Pmma material to repair caries

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.
