What causes tooth decay?
In short
Tooth decay starts when the bacteria in plaque turn sugars and carbohydrates into acids that attack the enamel. If it is not treated, the cavity spreads into the dentine and then the pulp of the tooth. Careful oral hygiene, less sugar and regular dental check-ups are the most effective prevention.
Yes, we knowβ¦ tooth decay is the most common condition affecting the mouthβ¦
But what exactly are cavities? If you are wondering what causes tooth decay and how to prevent it effectively, you are in the right place.
At NeaBios Dental Clinic, led by Dr Nihad Pljevljak, we welcome families every day from Rome EUR Laurentina and the nearby neighbourhoods of Tre Fontane, Torrino, Spinaceto and Cecchignola, offering clear answers and tailored solutions for every dental need.
In this article you will find a complete explanation of how cavities develop, together with practical advice to protect the whole family's smiles.
Why cavities form: the main causes
Tooth decay develops through a gradual process involving several factors. In our experience at NeaBios, our patients from EUR often ask us to explain this process in simple terms.
Cavities form when the bacteria in your mouth turn sugars and carbohydrates into acids. These acids attack the tooth enamel, first creating small lesions which, if left untreated, can progress until they reach the dentine and the pulp of the tooth.
The main factors that encourage tooth decay include:
- A diet high in sugar: sweets, fizzy drinks and snacks help bacteria multiply
- Poor oral hygiene: plaque that is not removed hardens into tartar
- Not enough saliva: a dry mouth reduces the teeth's natural protection
- Genetic predisposition: some people are naturally more susceptible
Dr Nihad Pljevljak has noticed that many families underestimate the importance of early prevention, especially for school-age children.
What to do straight away if you suspect a cavity
If you notice pain, sensitivity or dark spots on your teeth, it is important to act promptly. Our patients from Laurentina, Montagnola and Fonte Ostiense often get in touch with us worried about these symptoms.
Immediate steps you can take:
- Rinse with lukewarm water to ease the discomfort temporarily
- Avoid very hot or very cold food, which can make sensitivity worse
- Use a soft toothbrush so as not to irritate the area further
- Take a painkiller, following the instructions on the patient leaflet
When you should see a dentist urgently:
- Severe pain that does not settle with painkillers
- Swelling of the face or gums
- Fever together with toothache
- Pus or an unpleasant taste in the mouth
Remember that putting off treatment can turn a simple filling into a more complex and more expensive procedure.
Modern professional treatments for tooth decay
The treatment of tooth decay has made huge progress in recent years. At NeaBios we use advanced technologies designed for comfort and long-lasting results.
Treatment options available:
- Composite fillings: tooth-coloured materials that blend in naturally with your own tooth
- Ceramic inlays: for larger cavities, combining strength and good looks
- Dental crowns: when the structure of the tooth is compromised
- Root canal treatment: to save badly damaged teeth
The innovative technologies we use include:
- Laser therapy for less invasive treatment
- Computer-controlled anaesthesia for virtually painless treatment
- Digital X-rays for accurate diagnosis with lower radiation exposure
- Operating microscope for maximum precision
Our specialists keep constantly up to date with the latest techniques, so that patients from EUR, Cecchignola and Spinaceto receive excellent care.
Effective prevention for the whole family
Preventing tooth decay is the most effective and economical way to keep your mouth healthy. Families who follow our prevention programmes show a significant reduction in cavities.
Daily routine for adults:
- Brush three times a day with fluoride toothpaste
- Floss every evening to remove plaque
- Use an antibacterial mouthwash to complete your oral hygiene
- Watch your diet, cutting down on sugar and frequent snacking
Prevention for children:
- Supervise toothbrushing until around the age of 8
- Fissure sealants on the permanent molars
- Professional fluoride applications at check-ups
- Healthy eating habits, with healthy snacks such as fruit and vegetables
Recommended regular check-ups:
- A check-up every 6 months for adults
- A check-up every 3-4 months for children
- Professional dental hygiene every six months
- Yearly X-rays for early diagnosis
Conclusion: oral health as an investment for your family
Understanding what causes tooth decay is the first step towards protecting the whole family's oral health. As we have seen, cavities are the result of a process that can be prevented with good daily habits and regular check-ups.
At NeaBios, twenty years of experience have taught us that personalised prevention is the key to success. Every family has different needs, and we are committed to providing tailored solutions for every patient.
Oral health is not just about appearance: it is an investment in your overall wellbeing. Bacteria in the mouth can in fact affect heart health, the immune system and even cognitive performance.
Remember: a cavity treated promptly needs only a simple procedure, while a neglected one can compromise the whole tooth and cause severe pain.
