Sodium Fluoride
About Sodium Fluoride
Sodium Fluoride is a prescription medicine used to help prevent tooth decay and strengthen developing teeth. It is commonly prescribed for infants, children, and adolescents who live in areas where the natural fluoride content of drinking water is low. Fluoride helps strengthen tooth enamel, making teeth more resistant to the acids produced by bacteria that cause cavities. It may also help repair the early stages of tooth damage before cavities develop.
For the best results, take Sodium Fluoride exactly as prescribed by your dentist or healthcare provider. This medicine is usually taken once daily and may be taken with or without food, although it is often recommended at bedtime after brushing your teeth. Avoid eating, drinking, or rinsing your mouth for at least 30 minutes after taking the medicine, as this allows fluoride to remain in contact with your teeth for longer. Maintaining good oral hygiene, limiting sugary foods and drinks, and attending regular dental check-ups can further improve the protective effects of this treatment.
Most people tolerate Sodium Fluoride well when taken at the recommended dose. Mild side effects such as stomach upset or nausea may occasionally occur. However, seek medical attention immediately if you develop severe stomach pain, persistent vomiting, allergic reactions, or notice white, brown, or grey discolouration of the teeth, which may indicate excessive fluoride exposure.
Before starting this medicine, tell your doctor or dentist if you have kidney disease or if your household drinking water already contains adequate fluoride. Taking excessive fluoride over long periods may lead to dental or skeletal fluorosis. Do not take this medicine unless it has been specifically prescribed, particularly in children, as the correct dose depends on age and the fluoride concentration of the local water supply.
Certain medicines and supplements containing calcium, magnesium, iron, or aluminium may reduce the absorption of fluoride if taken at the same time. If you are pregnant, breastfeeding, or have any long-term medical conditions, consult your healthcare provider before using this medicine.
Uses of Sodium Fluoride
Medicinal Benefits
Taking Sodium Fluoride helps strengthen your teeth by increasing the resistance of tooth enamel to acid attacks from bacteria and sugary foods. Regular use, together with good oral hygiene and routine dental care, plays an important role in preventing cavities and maintaining healthy teeth throughout childhood and adolescence.
Key benefits of this medicine include:
- Helps Prevent Tooth Decay: Strengthens tooth enamel, making teeth more resistant to the acids that cause cavities.
- Supports Healthy Tooth Development: Provides fluoride during the years when permanent teeth are developing, helping build stronger and healthier enamel.
- Promotes Enamel Repair: Encourages remineralisation of weakened enamel, helping reverse the earliest stages of tooth decay before cavities become established.

View AllDrug Warnings
- Take only the prescribed dose: Fluoride supplements should only be taken if recommended by your dentist or healthcare provider. Taking more than the prescribed amount can increase the risk of dental or skeletal fluorosis.
- Know your water fluoride level: Your fluoride dose is based on the fluoride concentration in your local drinking water. Inform your dentist if you move to a different area or change your primary water source, as your dose may need adjustment.
- Separate mineral supplements: Calcium, magnesium, aluminium-containing antacids, iron supplements, and multivitamins can reduce fluoride absorption. Take these products at least 2 hours before or after your fluoride dose.
- Keep out of children's reach: Accidental ingestion of large amounts of fluoride can be dangerous for young children. Store the medicine securely and seek immediate medical attention if an overdose is suspected.
Drug Interactions
Sodium Fluoride may interact with certain medicines, affecting its effectiveness or reducing fluoride absorption.
- Calcium supplements: Calcium binds to fluoride in the digestive tract, reducing its absorption. Take these supplements at least 2 hours apart from Sodium Fluoride.
- Iron supplements and multivitamins containing minerals: Iron, calcium, magnesium, and zinc may reduce fluoride absorption if taken at the same time.
- Antacids containing calcium, magnesium, or aluminium: These medicines can decrease the absorption of sodium fluoride. Separate doses by at least 2 hours.
- Other fluoride-containing products: Using multiple fluoride supplements or medicines together may increase the risk of excessive fluoride intake and fluorosis unless specifically recommended by your healthcare provider.

Habit Forming
Diet & Lifestyle Advise
- Maintain good oral hygiene: Brush your teeth twice daily with a fluoride toothpaste and floss regularly to remove plaque and help prevent cavities.
- Limit sugary foods and drinks: Reducing your intake of sweets, sugary beverages, and sticky snacks helps lower the risk of tooth decay and enhances the protective effects of fluoride.
- Separate dairy products from your dose: Avoid milk, cheese, yoghurt, calcium-fortified foods, or calcium supplements for at least 2 hours before or after taking Sodium Fluoride, as calcium can reduce fluoride absorption.
- Visit your dentist regularly: Routine dental examinations and professional cleanings help monitor your oral health and ensure your fluoride treatment remains appropriate.
- Use fluoride products as directed: Avoid swallowing fluoride toothpaste or mouthwash, especially in children, to prevent excessive daily fluoride intake.
Patients Concern
Disease/Condition Glossary
Otosclerosis: It is a progressive hearing disorder caused by abnormal bone growth in the middle ear, especially around the stapes bone (one of the tiny hearing bones). Because of this abnormal growth, the stapes cannot vibrate properly, reducing the amount of sound that reaches the inner ear and causing hearing loss. Common symptoms include gradual hearing loss, often starting in one ear and progressing to both; difficulty hearing low-pitched sounds; tinnitus (ringing or buzzing in the ear); and dizziness or balance disturbances (rarely).
FAQs
Sodium Fluoride is used in the management of otosclerosis and helps reduce symptoms such as tinnitus (ringing in the ears) and imbalance associated with abnormal changes in the ear bones.
Sodium Fluoride contains Sodium fluoride, which reduces osteoclastic and increases osteoblastic bone formation. It slows bone resorption (the process by which bones are absorbed and broken down in the body), helps maintain bone density, and prevents excessive bone turnover in the middle ear. It helps restore normal bone metabolism in the bony part surrounding the inner ear and slows down the progression of the disease.
Yes, Sodium Fluoride reduces tinnitus (ringing in the ears) and imbalance associated with abnormal changes in the ear bones.
Sodium Fluoride is not recommended for chronic rheumatoid arthritis patients, as there may be an increase in joint symptoms during treatment, which subside after stopping.
Sodium Fluoride is prescribed for individuals diagnosed with otosclerosis to help slow its progression. It may be recommended for those in the condition's early stages or as part of a broader treatment plan. Please consult a doctor before using Sodium Fluoride to determine if it suits you.
Sodium Fluoride cannot reverse hearing loss caused by otosclerosis. However, it may help to slow disease progression by strengthening bone structure and reducing further damage. Please consult your doctor for personalised advice and treatment.
