Tooth decay remains one of the most common chronic diseases worldwide. This condition, which can affect all age groups from children to adults, is often not recognized at an early stage because it does not give any symptoms in the initial stage. A significant number of our patients who apply to our outpatient clinic in Sultanbeyli and surrounding districts seek treatment when the caries reaches the pain stage; however, problems that can be solved with a simple filling in the early period can be solved due to delay. root canal treatment or it may progress to tooth extraction.
This guide explains in a simple and understandable way how tooth decay occurs, what symptoms it gives, its stages and filling treatment options.
What is Tooth Decay (Caries)?
Tooth decay (medically known as caries) is the process of permanent damage caused by the acids produced by bacteria in the mouth by fermenting food residues, dissolving the hard tissues of the tooth - enamel, dentin and cementum - over time. This damage, which initially begins only in the enamel, the outermost layer of the tooth, can reach deeper tissue layers, nerve and vascular structures over time if left untreated.
According to the World Health Organization (WHO), more than 3.5 billion people globally are affected by dental caries. Similarly in Turkey, tooth decay ranks among the top oral health problems.
How Does Tooth Decay Occur?
Tooth decay is not caused by a single cause, but by a combination of four interacting factors:
- Bacteria: Various oral bacteria, especially Streptococcus mutans, form a layer of plaque on tooth surfaces.
- Carbohydrates: Sugar and starch-containing foods are fermented by bacteria, setting the stage for acid production.
- Tooth surface: Sensitivity to acids varies from person to person and even from tooth to tooth; enamel thickness and mineralization quality are decisive.
- Time: It takes time for the bacteria to produce acids and for the acids to dissolve the tooth, a process that is accelerated by lack of cleaning.
When these four factors are present together and for a sufficient period of time, caries becomes inevitable. After every meal, a temporary acid environment forms in the mouth; saliva neutralizes this acid. However, incessant snacking or inadequate oral hygiene disrupts this balance and enamel erosion begins.
Stages of Tooth Decay
Tooth decay progresses in four main stages. The stage at which it is detected directly determines the treatment option and difficulty.
| Phase | Affected Tissue | Symptom | Treatment |
| Phase 1 - Mine | Outermost hard layer of the tooth | Usually no symptoms; white or brown spot | Fissure sealant, fluoride application |
| Stage 2 - Dentin | The soft layer under the enamel | Sensitivity to hot and cold, mild pain | Filling (composite / amalgam) |
| Stage 3 - Pulp | Tissue containing nerves and vessels | Spontaneous, throbbing pain | Root canal treatment or extraction |
| Stage 4 - Abscess/Root | Root tip and surrounding tissues | Swelling, fever, facial pain | Canal + antibiotics / extraction |
Critical information: While a Stage 1 cavity can be stopped with fluoride application or fissure sealant, a Stage 3 cavity requires root canal treatment. Early detection significantly reduces both the cost of treatment and the discomfort experienced by the patient.
Risk Factors for Tooth Decay
Some individuals are more prone to tooth decay. Knowing these risk factors can be a guide in taking preventive measures:
- Poor oral hygiene: Lack of regular brushing and flossing accelerates plaque build-up.
- Frequent and excessive consumption of sugar: Sticky, sugary foods and acidic drinks in particular perpetuate acid production.
- Dry mouth (xerostomia): Saliva is the natural acid buffering mechanism; when its flow is reduced, the risk of caries increases. Some medications can cause dry mouth.
- Deep fissures Pits and crevices on the grinding teeth can become a shelter for bacteria.
- Fluoride deficiency: Fluoride increases the resistance of enamel to acids; inadequate fluoride exposure increases the risk of caries.
- Don't sleep with pacifiers and bottles in childhood: Exposure of teeth to sugary liquids during the night leads to ‘bottle cavities'.
- Pregnancy: Hormonal changes and acid exposure due to vomiting can increase the risk of caries.
- Diabetes and chronic diseases: Changes in saliva composition can increase the risk of caries.
Symptoms of Tooth Decay: When to Recognize?
The insidious characteristic of tooth decay is that it is almost asymptomatic in its initial stages. Symptoms usually appear when the decay approaches the dentin layer or the pulp:
- Visible brown, black or white stain or pitting on the tooth
- Temporary sensitivity to sweet, hot or cold
- Pain that does not go away for a long time after a cold (may indicate pulp involvement)
- Pain or pressure during chewing
- Food stuck between the teeth
- Spontaneous onset, throbbing pain (advanced caries)
- Bad breath or bitter taste in the mouth
| ⚠ IN CASE OF THESE SYMPTOMS, CONTACT YOUR DENTIST IMMEDIATELY |
| Spontaneous throbbing pain, If it worsens, especially at night, and is accompanied by swelling of the face or fever, urgent dental evaluation is necessary. These symptoms may indicate a dental abscess, which risks developing into a serious infection that can sometimes spread to the neck and throat. |
How is Tooth Decay Diagnosed?
Clinical examination and imaging are used together to diagnose caries:
- Visual and probe examination: Visual and fine instrument (probe) examination of tooth surfaces; detection of pitting and softening.
- Bite-wing x-ray: Indicates early caries on interdental surfaces and secondary caries below the filling margin. Sana Medical Center Radiology Unit It performs these evaluations with its digital x-ray infrastructure.
- Transillumination and laser fluorescence: Technologies that detect early enamel caries; can reveal caries that cannot be detected by visual examination.
- Panoramic X-ray: Used for an overall assessment of the whole mouth; allows multiple teeth to be examined at the same time.
| 💡 EXPERT NOTE - FROM THE ORAL AND DENTAL HEALTH UNIT |
| A common situation in our outpatient clinic: Caries on the interdental surfaces can be missed during routine examinations. Twice-yearly control x-rays allow us to detect early caries that cannot be detected on visual examination. A pain-free tooth does not necessarily mean a cavity-free tooth. |
What is Filling Treatment? Which Materials Are Used?
Filling treatment; It is the process in which the shape, function and aesthetics of the tooth are restored by filling the cavity formed after the decayed tissue is removed with a suitable restorative material. Filling, which is the most common restoration method in dentistry, can be used for many years without any problems with the right choice of material and oral hygiene.
| Filling Type | View | Resilience | Most Suitable Region |
| Composite (White) | Compatible with tooth color | 7-10 years (longer with proper care) | Front and back teeth |
| Amalgam (Silver) | Metallic, silver gray | 10-15 years | Posterior molars |
| Ceramic inlay/onlay | Natural color, high aesthetics | 15+ years | Large caries, back teeth |
| Glass ionomer | Close to tooth color, F oscillation | 5-7 years (low print area) | Children's teeth, neck region |
Composite (white) fillings are the most widely preferred material today because they can be used in both front and back teeth and provide a natural appearance. Amalgam fillings, on the other hand, are still used especially in the molar areas due to their long life and resistance to high pressure; however, their preference is gradually decreasing due to aesthetic concerns.
How is Filling Treatment Performed?
- Local anesthesia: The area to be treated is numbed; standard filling procedures are painless.
- Carious tissue removal: Using special burs and dental instruments, decayed enamel and dentin tissue is thoroughly removed.
- Surface preparation (acid application): If a composite filling is to be made, the surface is roughened with acid; this step strengthens the adhesion of the filling to the tooth.
- Bonding agent application: A bonding agent is applied and cured with polymerization light.
- Filling application: The selected filling material is placed layer by layer and each layer is hardened with a special light.
- Shaping and occlusion check: The filling is shaped to match the opposing teeth; the bite balance is checked.
- Polishing: The surface is smoothed; this step improves both aesthetics and long-term durability.
Duration: The filling of a single tooth is usually completed between 30-60 minutes. Since more than one tooth may need to be treated in the same session, the total time may vary.

Filling, Root Canal Treatment or Extraction?
The treatment option is determined by the stage at which the caries was caught. This decision is only possible through clinical examination and radiological evaluation.
| Caries Stage | Treatment Considered First | Description |
| Phase 1 (Mine) | Fluoride / Fissure sealant | You may not even need a filling |
| Stage 2 (Dentin) | Filling (composite / ceramic) | Standardized, comfortable operation |
| Stage 3 (Pulp) | Root canal treatment + crown | The tooth is saved if the nerve tissue can be preserved |
| Stage 4 (Abscess/Root) | Canal + antibiotics or extraction | Infection control is a priority |
For a caries that has reached stage 3 root canal treatment can be applied to save the tooth. When extraction becomes mandatory, the cavity dental implant or closure with a bridge is evaluated. Bringing the treatment sequence to an early stage significantly reduces both the patient's discomfort and the cost of treatment.
Tooth decay in children: Why are Milk Teeth Important?
Since deciduous teeth are temporary, it may be thought that they are not important when they decay; however, this common misconception can have serious consequences for children's oral health. Primary teeth play critical roles in chewing, speech development and as placeholders for permanent teeth. A deciduous tooth lost at an early stage can lead to the misplacement of the permanent tooth underneath.
The most common form in children is bottle caries; overnight contact with sugary liquids (milk, fruit juice) causes rapid and widespread decay of the front teeth. In school-age children, frequent snacking and inadequate brushing accelerate the development of caries in the fissure areas of the back teeth.
For questions about dental health in children Child Health Unit and our Oral and Dental Health specialists can make a coordinated evaluation.
How to Avoid Tooth Decay?
Tooth decay is a largely preventable disease. The following steps can significantly reduce the risk of tooth decay:
Daily Oral Hygiene
- Brushing: Brushing should be done at least twice a day with a soft bristle brush using toothpaste containing fluoride. Each brushing should last at least 2 minutes and the brushing angle should be positioned at 45° to the gingival line.
- Flossing: Flossing or using an interdental brush once a day removes plaque from surfaces that the brush cannot reach.
- Mouthwash: Fluoride mouthwashes provide additional protection, especially in individuals at high risk of caries.
Nutrition Habits
- Limit consumption of sugary and acidic foods and drinks: Frequent snacking, especially between meals, leads to a prolonged acid environment in the mouth.
- Increase water consumption: Water washes the mouth and dilutes acids; fluoridated tap water in particular supports enamel health.
- For nutritional recommendations to support dental health Nutrition and Dietetics Unit‘You can also contact our.
Professional Protective Applications
- Twice-yearly dental check-ups: For detection of early stage caries and scaling.
- Fluoride application: Professional fluoride gel or varnish application can be performed by the dentist, especially in children and adults with high caries risk.
- Fissure sealant: This closes the deep pits of the back teeth and creates a strong protective barrier, especially in children.
| 💡 EXPERT NOTE - FROM THE ORAL AND DENTAL HEALTH UNIT |
| The majority of patients come for check-ups once a year or less. However, the enamel stage of caries can progress silently for months or even years. Twice-yearly check-ups make it possible to catch the caries at the filling stage and prevent root canal treatment to a great extent. The absence of pain in your mouth does not mean that there is no problem. |
Early Diagnosis, Simple Filling; Late Diagnosis, Long Treatment
Tooth decay is a disease that tends to progress rapidly but can be intervened very easily in the early stages. While a decay that has reached the enamel stage can be stopped with fluoride application; a decay that has reached the pulp root canal treatment, or shooting or implant such as the development of a new economy.
Regular oral hygiene and twice-yearly dental check-ups are the most powerful steps to make that difference. Making an appointment without waiting for pain is the most effective way to save both your time and your health.

Frequently Asked Questions
Does tooth decay go away on its own?
No, it is not. Tooth decay is an irreversible process of damage and does not heal on its own. A very early stage of decay (at the white spot stage on the enamel surface) can be stopped by promoting mineralization with fluoride application; however, the resulting pit or cavity can only be repaired with a filling.
Is filling treatment painful?
No; no pain is felt during the filling procedure after local anesthesia is applied. After the procedure, mild sensitivity may be experienced for 1-2 days as the anesthesia wears off; this is expected. If the pain exceeds 48 hours, it is recommended to consult your physician.
How long does the filling last?
Depending on the material used and the size of the decay, a single filling is usually completed in 30-60 minutes. This time may be longer if more than one tooth is to be treated in the same session.
Is white filling or amalgam filling more durable?
Amalgam fillings continue to be a long-term option (10-15 years), especially in large molar areas. Composite white fillings, on the other hand, offer an aesthetic advantage with a lifespan of 7-10 years; this period can be extended with proper care and regular control. Which material is more suitable is determined together with your physician according to the size and location of the cavity and the patient's preference.
My child's baby tooth has decayed, do I need treatment?
Answer. Decayed baby teeth can cause pain and damage the health of the permanent tooth underneath. Early treatment also protects the child's speech and chewing development. For your child's dental health Oral and Dental Health Unit‘for more information.
How often should I go to the dentist?
For adults at moderate caries risk, two check-ups per year are recommended. For individuals with high caries risk (dry mouth, diabetes, history of active caries), this interval can be shortened to 3-4 months. Your physician will assess your individual risk and determine the appropriate frequency of check-ups.
Is tooth decay covered by insurance?
