Pit and fissure sealing is a common dental procedure performed to prevent dental caries, especially in children. The occlusal surfaces of teeth—especially the molars—often contain deep pits and fissures that tend to retain food debris and plaque. These areas provide a favorable environment for bacterial accumulation, significantly increasing the risk of dental caries. Let’s take a closer look at a real clinical case at Herident dental clinic demonstrating this procedure.
1. Overview of the Treatment Case
Patient D.P.C., female, 12 years old, was brought to Herident Dental Clinic by her parent due to suspected caries in the permanent molars. This group of teeth plays a crucial role in the chewing function and is also a common site for plaque accumulation due to their deep and complex pit and fissure anatomy.

Khi đến nha khoa, bệnh nhân có biểu hiện lo lắng và sợ đau – một tâm lý phổ biến ở trẻ nhỏ khi tiếp xúc với môi trường nha khoa. Sau khi thăm khám, bác sĩ đã chẩn đoán các răng hàm lớn vĩnh viễn của bệnh nhân đều có hố rãnh sâu – nguy cơ cao hình thành sâu răng trong tương lai. Phương pháp trám bít hố rãnh đã được lựa chọn để can thiệp sớm, nhằm ngăn ngừa tổn thương men răng và bảo vệ cấu trúc răng tự nhiên.
2. Patient's Expectations
The parents expressed a desire for their daughter to receive early prevention against cavities, aiming to maintain healthy teeth for the long term without needing complex treatments in the future.
Meanwhile, D.P.C. was anxious about visiting the dentist, especially worried about feeling pain or discomfort during the treatment.
Therefore, the parents hoped to find a gentle, safe, non-invasive, and especially painless solution that would help their child cooperate easily and develop a positive oral care routine.
3. Initial Condition
Patient: D.P.C. – Female, 12 years old. The patient has no history of systemic medical conditions, her health is stable, and she has no previous history of extensive dental treatments.
Through clinical examination and X-ray analysis, the dentist noted that the patient's permanent molars, including R16, 17, 26, 27, 36, 37, 46, and 47, exhibited deep, narrow, and complex anatomical pits and fissures.
Expected Impact: These areas are prone to food accumulation and difficult to clean with a regular toothbrush, which increases the risk of developing cavities in the near future.
4. Diagnosis & Treatment Indication
Diagnosis by the Dentist:
The patient has complex pits and fissures on the permanent molars, with a high risk of cavities if early preventive intervention is not performed.
Treatment Plan:
The optimal treatment plan recommended by the dentist is the application of pit and fissure sealants on the permanent molars—a preventive dental technique that smooths out deep grooves, preventing food and bacteria from accumulating, thereby reducing the risk of cavities by up to 90%.
Compared to waiting for cavities to occur and then performing restorative treatments or root canal therapy, this procedure:
Quick, painless, and does not require anesthesia.
Much more cost-effective compared to more complex treatments in the future.
Absolutely safe for children.
5. Treatment Procedure
The entire pit and fissure sealing procedure was completed in a single visit and included the following steps:
- The dentist examined and assessed the condition of the teeth.
- The tooth surfaces were cleaned using specialized instruments without damaging the tooth structure.
- The pits and fissures were conditioned with a mild acid solution to enhance the bonding strength.
- Sealant material (glass ionomer or composite resin) was applied to the pits and fissures.
- A curing light was used to harden the material.
- The occlusion was checked and adjusted if necessary to ensure comfortable chewing.

The entire procedure takes approximately 5–7 minutes per tooth, requires no anesthesia, causes no discomfort, and is perfectly suited for young children.
6. Treatment Outcome & Follow-up
After treatment, the deep pits and fissures on the occlusal surfaces of the molars were filled, creating a smooth surface that is easier to clean.

D.P.C. was cooperative, cheerful, and showed no signs of fear during the procedure. The parents were satisfied as they no longer had to worry about potential cavities while ensuring their child’s comfort.
7. Professional Opinion
Pit and fissure sealing is an effective preventive dental treatment, especially for children and teenagers. These age groups are more likely to develop cavities in their permanent molars due to the deep grooves and small fissures in their teeth, as well as the lack of proper oral hygiene habits.
The indication for pit and fissure sealant is especially important in cases such as:
- Teeth with complex, deep pits and fissures that are difficult to clean (as seen in patient D.P.C.).
- Young children who have not yet developed the awareness or skills to brush their teeth properly.
- Children with a diet rich in carbohydrates and sugars.
- Children with a high risk of dental caries due to familial or environmental factors.
Is pit and fissure sealing painful?
This is a common question from both parents and young patients. In fact, pit and fissure sealing is a completely painless procedure that does not require anesthesia and does not involve the invasive removal of tooth structure. The reason for this is:
- There is no drilling or removal of tooth enamel; only the surface is cleaned and treated gently.
- No anesthesia or needles are used, which children are often afraid of.
- The procedure is quick, taking an average of only 5–7 minutes per tooth.
- There is no post-treatment sensitivity, and children can eat and drink normally right afterward.
Therefore, this method is extremely suitable for young children—it helps create a positive attitude towards dental visits and prevents future dental anxiety.
Key benefits of pit and fissure sealing:
- Effective cavity prevention: Especially in the molars, where plaque tends to accumulate.
- Painless and comfortable: Children cooperate well, without fear or discomfort.
- Non-invasive: Preserves the natural structure of the tooth.
- Quick and time-saving: The procedure is completed in a single visit.
- Cost-effective and long-lasting: The cost is lower compared to cavity treatments, and the effectiveness lasts for many years with proper care.
- Increases oral health awareness: Children are educated on the importance of early tooth protection, laying the foundation for long-term oral health.
