How much does Sf cost without insurance?

Without insurance, the cash price of Sf at most pharmacies will be $19.94 per 1, 56gm of 1.1% tube. With a SingleCare prescription discount card, you can pay $7.46 for an Sf prescription at one of many participating pharmacies.

How much does Sf cost with insurance?

The copay cost of Sf may vary depending on your insurance plan. In some cases, your health insurance plan may not cover Sf. However, if you have dental insurance, you may have coverage for prescription sodium fluoride. Talk to your insurance provider to determine the cost of your prescription with insurance.

With a SingleCare prescription savings card, Sf costs $7.46. If you fill your Sf prescription at a pharmacy, ask your pharmacist about your insurance status. You can also ask your pharmacist to compare your insurance copay to the price with a SingleCare discount to ensure you pay the lowest price. Your Sf price with a SingleCare Sf coupon at participating pharmacies could be lower than the price with insurance.

Does Medicare cover Sf and how much does it cost?

Medicare Part D and Medicare Advantage prescription drug insurance plans usually do not cover Sf. Instead, Sf is typically covered by dental insurance and is often supplied by a dentist who purchases it from specialty pharmacies. For Medicare patients, SingleCare offers Sf coupons that can reduce the cost of prescription sodium fluoride gel to $7.46.

What is the brand name of Sf?

SF is a generic prescription high fluoride gel. Brand-name high fluoride gels include Prevident Brush-On Gel, Dentagel, and X-PUR NaF Gel. You can search for any of these medications on the SingeCare website or app for additional information or savings opportunities.

What is Sf?

Sf is a generic prescription high fluoride gel for patients who have a high risk of developing cavities or tooth decay. The active ingredient in Sf is sodium fluoride, but it has greater quantities of fluoride than over-the-counter fluoride toothpaste. Sodium fluoride strengthens tooth enamel and prevents cavities.

Most fluoride toothpaste contains between 1,000 to 1,500 parts per million of sodium fluoride. Sf contains 5,000 ppm of sodium fluoride.

Sf is applied at night after brushing your teeth. It is applied as a thin strip on your teeth using a toothbrush or mouth tray. Leave the gel on for one minute. Then, spit it out and do not swallow. Children should rinse their mouths thoroughly after use. Do not eat for at least 30 minutes following application.

Children under the age of 6 years old should not use Sf unless instructed to do so by a dentist or healthcare provider. 

What are the side effects of Sf?

Used as directed, Sf will rarely cause side effects. Mouth or gum irritation is possible, but rare side effects while using Sf. Allergic reactions are rare but may manifest with signs or symptoms such as rash, hives, trouble breathing, or swelling of the face, tongue, or throat. 

Sf, like non-prescription fluoride toothpaste, will have side effects if swallowed. Overdose symptoms include nausea, vomiting, drooling, diarrhea, numbness, tingling, seizures, and muscle weakness. Do not swallow Sf, but rather spit it out after use.

Consult your doctor or healthcare professional for additional information and medical advice regarding other possible side effects or drug interactions.
