If you are in Vancouver and think that you need a filling, then book an appointment with Dr. Alavi at Hemlock Dental Clinic now, fill out the online form, and have a quick check-up.

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.​

Example Time Ranges by Situation


How long does it take to fill a cavity? This table gives a general idea of realistic time frames; your actual time with Dr. Alavi at Hemlock Dental Clinic will depend on your specific exam and X-rays.​

Situation (per visit) Typical chair time Notes
Single small cavity on an easy‑to‑reach tooth 20–30 minutes​ Minimal drilling, quick composite placement, often done during a routine visit.
Medium cavity on a back tooth 30–45 minutes​ Slightly more decay removal and shaping, extra time to check bite.
Large cavity or multiple surfaces 45–60+ minutes​ Deeper decay, layered filling, more detailed shaping and polishing.
Two or more cavities in one session 45–90 minutes total​ Dentist may treat several teeth in one visit if you prefer.
New patient exam plus first filling Around 60–90 minutes​ Includes full assessment, X‑rays, and a personalized treatment plan.

 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?


Most cavity fillings are quick and straightforward.

Typically, the procedure takes 20 to 60 minutes, depending on how big the cavity is and which tooth is affected. Treating cavities early helps keep the process fast and simple.

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.​

FAQs


How long does it take to fill a cavity from start to finish?
The filling itself occupies 20-60 minutes per tooth in most instances, and the overall visit (including numbing, X-rays, and instructions) lasts about 45-90 minutes.


Can I heal a cavity naturally instead of getting a filling?
Damage to very early enamel, when there is no real hole,  may sometimes be reversed by using fluoride, changing the diet, and good care.


 

How soon can I eat after a filling?
The composite fillings form when you walk out, and you can generally eat as soon as the numbness subsides; but, you should chew slowly and avoid hard food immediately.

I had an excellent experience at Hemlock Dental Clinic. I went there last week for a dental cleaning, and I was honestly very impressed with the quality of care. I have always been quite nervous about dental cleanings, but the dentist was extremely gentle, professional, and careful. The entire procedure was done without the slightest pain or discomfort, which was a wonderful surprise for me. I really appreciate the dentist and the entire team for making the experience so comfortable and stress-free. Thank you for the excellent care and professionalism. I highly recommend Hemlock Dental Clinic to anyone looking for a caring and professional dental clinic.

I had a dental emergency. The dentist cancelled her own lunch to accommodate me (she never told me this but the front desk confirmed it). The dentist listened to my concerns and expertly fixed the problem. Honestly, I would give more than 5 stars if I could. I'm really grateful!

The first time I visited this clinic I showed up when they were closing, Zhina kindly let me in and Dr. Alavi checked my teeth patiently. After that, Dr. Alavi and her great assitants Maryam and Anandi, fixed my prolonged and difficult teeth problem in several very pleasant appointments. Dr, Alavi's skill and expertise are impeccable and most importantly, she really cares about her patients. Niki also always goes out of her way to help me out, doing extra work to make sure I get the best for my teeth, she also speaks madarin! Pendar is good at cleaning teeth too. Can't wait for my teeth to rot and I can give this great clinic another visit! ha

Excellent dental care. The male hygienist is friendly, professional and relaxed. Front desk staff and the dentist are wonderful. Prices align with the B.C. fee guide. They make sure that insurance is billed correctly. So happy that I switched to this dentist a couple of years ago.
