Back to work

Due to unforeseen events, our clinic is still closed. Dr. Witzu recently had a serious accident which resulted in a spinal injury.


Dr. Witzu is doing well and is currently in rehabilitation and slowly mending. Dr. Kwong Hing from Sudbury Smiles Dentistry had graciously agreed to see anyone who needs to make an appointment before our clinic re-opens. Dr. Hing can be reached at 705-522-0220 ext. 1. Alternatively, if you have a dental emergency, you can contact the emergency on-call dentist at 249-869-1072.


We’d like to thank you for your continued patience.


Thank you,

On behalf of Dr. Witzu and the staff at Chelmsford Family Dentistry

Silver Amalgam Fillings from

Chelmsford Family Dentistry

Gold and silver amalgam fillings have been used by dentists for nearly two centuries, however in recent years some critics have argued that they are unsafe and should not be used because they may cause mercury poisoning or other problems and are damaging to the environment.

Safe and Effective

The FDI World Dental Federation, as well as dental associations and dental public health agencies around the world are of the opinion that silver amalgam fillings are safe and effective. Consumer Reports magazine has suggested that opponents of amalgam fillings are using pseudoscience to frighten patients into choosing more expensive treatment options.

Some of the advantages offered by silver amalgam fillings over resin cosmetic fillings are:

  • Durability– Amalgam fillings typically last twice as long as resin composite fillings.
  • Convenience– Amalgam fillings are easier to place than composite fillings. They are also much more tolerant of contamination caused by blood or saliva.
  • Price– Amalgam fillings typically cost 20% to 30% less than resin composite fillings.

We will be happy to address any questions or concerns you might have about amalgam dental fillings. Please contact our office for more information or to schedule a consultation appointment.
