What Affects How Long a Filling Takes?


How long do cavity fillings take? Some factors will change the duration of time you are seated in the chair is different according to some factors:

Cavity size and depth

  • Small cavities require less drilling and less material, which makes them the fastest (often 20-30 minutes).
  • Greater or broader cavities are slow to clean and to be rebuilt in layers, so they will last for 45-60 minutes.

Tooth location and access

  • The front teeth, or those that are easily accessed, are usually quicker.
  • Hind teeth, or tooth gaps, need more time since the dentist requires more specific tools and time in moulding the filling to allow you to floss correctly.

Number of cavities per visit

  • One filling: It is frequently 20-30 minutes per tooth.
  • Two or three fillings in one session may add to the total time to 45 or 60 minutes or more, depending on the complexity.

Filling material

  • Tooth‑coloured composite fillings are cured with a special light in a few seconds per layer, and the filling is hard by the time you leave.​
  • Amalgam (silver) fillings reach full strength over about 24 hours, so biting on hard foods should wait, even though placing them is still usually under an hour.​

 Typical Filling Timeline (Step by Step)


Here are some steps for a tooth filling Vancouver:  

  1.   Before treatment

The review of medical history, a quick discussion of what is wrong with you, and, in most cases, an X-ray to check on the cavity and depth. The dentist will tell how can you heal a cavity. Numbing (local anesthetic) around the tooth, which normally takes several minutes to take full effect.

  1.   Treating the cavity

The dentist softly eliminates the softened, infected section of the tooth, and molds the space in such a way that the filling will stick.

Then, rinsing and disinfecting of the cavity is done to decrease bacteria before the introduction of the filling.

  1.   Placing the filling

Composite fillings are applied in very fine layers, and each layer is left to harden by blue light in a few seconds. The dentist will shape the material to fit your tooth and bite, and polish the material to be smooth when you run your tongue over it.

  1.   Final checks and instructions

You bite on coloured paper so that the dentist can fix out any high spots, which will prevent soreness in the future. You also receive information regarding diet, hydration, and the normal sensitivity level in the following days.

How Long Do Fillings Last?


Durability of typical filling materials is:

  •       Filling (white) Composites usually last approximately 5-10 years with proper maintenance.
  •       Amalgam may be as long as 10-15 years, whereas ceramic or gold restorations can be 15 and longer, but might need more planning and two visits.

Can a Cavity Heal Without a Filling?


Very early changes in enamel (no hole yet) may sometimes be remineralized by using fluoride, good oral care, and diet modification. When there is an actual cavity, the tooth is unable to regenerate the lost structure; a filling or other restoration is required to prevent the loss and to protect the tooth.

How to support remineralization and prevent new fillings?


  • Brush twice daily with fluoride toothpaste, limit sugary and acidic snacks, and drink water regularly to support saliva.​
  • Regular checkups at a dental clinic in Vancouver help catch problems early, when conservative treatments are still possible.​
