what exactly is a tooth bonding?

Well, i can't say anything GumHelper (above) didn't!  So kudos there, GH - if you want a job in new hampshire, let me Know!!  :)\n\nsome people confuse bonded fillings with bonded veneers.  A filling is as described; sometimes to achieve the esthetic effect desired, a filling won't work; you need to make porcelein facade, which is NICER but way more expensive (like 700 inst of 120 dollars...)

Dental sealants are applied to the molars in one's mouth to prevent cavities. It is white so that it stays consistent with tooth color and it is a painless process.

composite bonding is the use of attaching two materials together with a two-part adhesive material.  Composite = made up of 2 or more materials.

That is the beginning of fixing it.  In addition to having the root canal done, you are also going to need to have a crown placed.  Then your tooth will be as good as new.  :)

A covalent bond is a bond in which the atoms making up the resulting molecule "share" the electrons in the form of covalent bonds.\nAn ionic bond is an extremely one sided "sharing" of electrons, so one sided, one atom is said to have completely stripped of an electron from another atom.\n\nWhat determines if the bond is covalent or ionic is the difference in the electronegativities of the two atoms bonding.  If the electronegativity difference is high enough, the bond is said to be ionic.  If the difference in electronagativities is significant, but not quite to the level of a full ionic bond, the bond is said to be polar (which may or may not mean that the resulting molecule is polar, this depends on several things).\n\nLooking at a chart of [Pauling] electronegativities,\nhttp://www.psigate.ac.uk/newsite/reference/plambeck/chem1/p01244a.htm\none can see that most elements are somewhere in the 1 to 2 range, with only a few elements getting much lower or higher than this value.  Unless the difference is high enough (usually a difference of about 1.5 is considered ionic), then the bond will just be polar, or less so.\n\nSo, all elements have the potential to theoretically bond ionically, but only in certain combinations with other elements.\nFor example, you will never see an ionic bond between Carbon and Hydrogen since the difference is just .4, but an ionic bond between Lithium and Fluorine is easy to make with a huge difference of 3.0.

Usually between $800 and $1400 per tooth.  It depends on the dentist, his overhead, lab costs, type and cost of the bonding agent (cement) he uses, labor costs, his talent and educational level...\n\nFor the most part, you do get what you pay for, so don't go to the cheapest one, or you'll be wasting you money.

The tooth is basically encased in bone. They usually cut away the "roof" of bone and a little bit around the tooth to get it out. The hole that is left over usually fills back in with bone and shouldn't cause any problems.

dna ligation is the joining of linear dna fragments together using covalent bonds. more specifically, dna ligation involves creating a phosphodiester bond between the 3' hydroxyl end of one nucleotide and the 5' phosphate of another.

Root canals are the long passages full of soft tissue deep within the dentin of a tooth, adjoined the pulp chamber. In dentistry, a pulpectomy is an endodontic treatment to cure an infection of the root canal; informally a root canal. A root canal, coupled with internal tooth bleaching, is also used to fix teeth that have blackened due to infiltration of decayed soft tissue into the dentin in the teeth, most often seen in frontal incisors that have been injured through a sudden impact.\n\nAt the center of a tooth is a hollow area that houses soft tissue, known as pulp. This hollow area contains a relatively wide space towards the chewing surface of the tooth called the pulp chamber. This pulp chamber is connected to the tip of the root of the tooth via thin hollow pipe-like canals—hence, the term "root canal". Human teeth normally have one to four canals; teeth toward the back have the most canals. These canals run through the centre of the roots like pencil lead runs through the length of a pencil. The tooth receives nutrition through the blood vessels and nerves traversing these canals. Occasionally, a cavity on the outside of the tooth may allow this soft tissue to become infected. If left untreated a serious jaw infection can result. The infection and inflammation is very painful in most cases. Ideally treatment should take place before this happens.\n\nTo cure the infection and save the tooth, it is necessary for the dentist to open into the pulp chamber, and remove the infected pulp by scraping it out of the root canals. Once that is done, the dentist fills the cavity with an inert material, usually Gutta-percha, and seals up the opening. This procedure is known as root canal therapy. If enough of the tooth is damaged by the disease or removed as a result of the treatment, a crown may be required.

Ask your dentist if bonding would be an option - it is less expensive. \n\n(Alternately, if you are comfortable with the idea and are willing to go outside of the US, dental procedures can be much less expensive. For example my sister goes to a US trained dentist in Mexico and pays 50-75% less, but you'd need to do lots of research to pick a dentist right for you.)\n\nHope this helps - good luck!

Ionic bonds are comprised of a metal and a non-metal.\nCovalent bonds are comprised of two bonded non-metals.

They don't hurt, but it is a procedure that takes a series of appointments over a few months.  They have to imbed the screw that will hold the tooth and let that heal. Then they have to make the tooth to match your others.  The last step is attaching the completed tooth to the screw.  Implants are incredibly expensive.

Yes, it is possible; however, this is only limited to small procedures.  If there is a small amount of decay around a particular part of a veneer, often this decay can be removed and repaired with a bonded filling.  BUT, if the decay has spread underneath the veneer and your dentist is unsure that they can remove it all with the veneer in place, then the veneer will have to come off and be redone after all of the decay is removed.  Also, if too much tooth structure has to be removed around the veneer, then it will have to be redone as well, because you do not want to undermine the existing tooth structure too much!  Hope that this proves helpful!

A covalent bond\nThe other is an Ionic Bond which is when one atom gives an electron to another atom.

Molecular bonding.\n\nThis is a function of the atomic weight (protons in the nuclei) and the distrobution of the electron shell.  Give me three years and I will explain it fully.

Cavity. That's the word no one wants to hear at the dentist's office. A cavity (say: kah-vuh-tee) develops when a tooth decays (say: dih-kaze), or breaks down. A cavity is a hole that can grow bigger and deeper over time. Cavities are also called dental caries (say: kar-eez), and if you have a cavity, it's important to get it repaired.\n\nBut why would your tooth develop a hole? Blame plaque. That's a sticky, slimy substance made up mostly of the germs that cause tooth decay. The bacteria in your mouth make acids so when plaque clings to your teeth, the acids can eat away at the outermost layer of the tooth, called the enamel (say: ih-nah-mul). \n\nIf you don't go to the dentist, the acids can continue to make their way through the enamel, and the inside parts of your tooth can begin to decay. If you've ever had a toothache or heard an adult complain about one, it may have been because there was a cavity that reached all the way inside a tooth, where the nerve endings are. Ouch!\n\nYour dentist will carefully examine your teeth and may take X-rays. If your dentist discovers a cavity, he or she can repair it for you by first removing the rotted part of your tooth with a special drill. The dentist then fills the hole in your tooth with a special material. It's called a filling. \n\nDoes it hurt? Sometimes it does, but your dentist can give you an anesthestic. That's a kind of medicine that will numb the area around the problem tooth while you're getting your new filling.
