Based on the chemical formula, what type of compound is sodium fluoride (NaF)? Why?

Sodium fluoride is an ionic compound because it is composed of a positive and negative ion (metal and nonmetal). A metallic compound would have multiple metal atoms bonded to each other.
Sodium fluoride is a covalent compound because it contains multiple nonmetals, sodium and fluorine. A metallic compound would have multiple metal atoms bonded to each other.
Sodium fluoride is a metallic compound because it is composed of a mixture with metal ions. An ionic compound would contain only two elements, a metal and nonmetal.
There is not enough information provided to determine the type of bond for sodium fluoride.

I believe that NaF is an ionic compound

Yes, NaF is an ionic compound.

Is there any way to make it stop sticking to teeth and bones?

orrect to say that sodium fluoride (NaF) is an ionic compound.

The reason for this is that sodium is a metal (typically found in Group 1 of the periodic table) and fluorine is a nonmetal (typically found in Group 17). When a metal and a nonmetal combine, they form an ionic bond. In this case, sodium loses one electron to become a positively charged ion (Na+), while fluorine gains one electron to become a negatively charged ion (F-). The resulting ions are attracted to each other through electrostatic forces, forming an ionic compound.

To determine the type of compound based on the chemical formula, it is important to consider the elements in the compound and their locations in the periodic table. If the compound contains a metal and a nonmetal, it is likely to be ionic. If the compound contains only nonmetals, it is likely to be covalent. However, without additional information, it is not possible to determine the type of bond (ionic or covalent) within a compound.
