Dentistry Without Drill

The bravest among us feels terrified when hearing noise of a drill in dental office. Nowadays, there is a new drill-free dental technique which is used to remove dental caries as well as for other dental treatments; this technique is called Air Abrasion. The main idea of air abrasion is to utilize a mini sandblaster instrument which can spray the caries away. During the procedures of air abrasion, your dentist will aim a fine stream of particles (which are made of silica, aluminum oxide or baking soda) towards carious lesion of the tooth; compressed air or a gas which runs through a special hand-piece will push the particles towards surface of the tooth, the fine stream of particles will strike caries particles and remove them away.
teeth drillThough air abrasion technique is completely safe, some precautions must be made during it, including:
1.You must wear eye protectors to prevent your eyes from spray irritation
2.The dentist must use rubber dam to prevent from swallowing debris
3.A protective resin must be applied on the neighboring teeth and gum to protect them
4.All debris and particles must be suctioned to prevent you from breathing them into your lungs
In comparison with traditional drilling technique, air abrasion has many benefits, including:
1.Air abrasion produces no heat, no noise, no pressure, and no vibration.
2.Air abrasion limits the use of anesthesia in dental treatment, especially in simple cavities.
3.Air abrasion preserves the integrity of the remaining tooth structure
4.Air abrasion technique involves less moisture; this is an advantage when using tooth colored restorative materials, like composite and glass ionomer
5.Air abrasion restricts tooth chipping or micro-fractures
6.With air abrasion, the dentist can easily operate in many cavities during a single visit
7.The procedure of air abrasion are uncomplicated and rapid
While the disadvantages of air abrasion technique are:
1.Air spray in air abrasion technique sometimes causes sensitivity and pain to prepared tooth
2.Air abrasion can’t be used in deep cavities as it dangers the pulp
3.Air abrasion is only indicated in simple cavities which are confined to surface of the tooth
4.Composite filling material is the only type of filling materials used following air abrasion technique, as prepared cavities for amalgam filling need drill-cuts to retain amalgam restoration
cavity amalgamThere are many other uses of air abrasion technique; it can be used to remove old composite filling material, prepare surface of the tooth to receive sealants or bonding, and remove superficial tooth stains.
If you are dental phobic with minimal caries, then you are the best candidate for air abrasion.
