Dog Yellow Teeth & Tartar: Causes, Removal & Prevention Guide

Why Are My Dog's Teeth Yellow?

Yellow teeth in dogs are extremely common, but they're not something to ignore. That yellowish or brownish discoloration is usually caused by tartar (also called calculus) - hardened plaque that has mineralized on the tooth surface.

Understanding what causes yellow teeth and how to address it can save your dog from painful dental disease and you from expensive veterinary bills.

What Causes Yellow Teeth and Tartar in Dogs?

The Plaque-to-Tartar Timeline

1. Within hours: Bacteria in the mouth form a sticky film called plaque
2. 24-72 hours: Plaque begins to harden if not removed
3. 3-5 days: Plaque mineralizes into tartar
4. Once hardened: Tartar cannot be removed by brushing alone

Contributing Factors

• Lack of dental care: No brushing or dental treats
• Diet: Soft food diets promote plaque buildup
• Age: Older dogs accumulate more tartar
• Breed: Small breeds are more prone to tartar
• Genetics: Some dogs are predisposed to dental issues
• Crowded teeth: Create hard-to-clean areas

Stages of Tartar Buildup

Stage 1: Light Yellowing

• Thin layer of plaque/early tartar
• Mainly at the gumline
• Still reversible with home care

Stage 2: Moderate Buildup

• Visible yellow/brown deposits
• Covers more tooth surface
• May have mild gum inflammation
• Professional cleaning recommended

Stage 3: Heavy Tartar

• Thick brown/gray deposits
• Covers most of tooth
• Gums are red and inflamed
• Professional cleaning required

Stage 4: Severe Buildup

• Extensive tartar covering teeth
• Gum disease present
• Possible tooth damage
• Extraction may be needed

How to Remove Tartar from Dog Teeth

What You Can Do at Home

Important: Once tartar has hardened, it cannot be completely removed at home. However, you can:

1. Brush daily to prevent new buildup
2. Use dental chews - VOHC-approved options
3. Try dental water additives - Help reduce bacteria
4. Feed dental diets - Kibble designed to scrape teeth

What Requires Professional Help

• Thick, hardened tartar deposits
• Tartar below the gumline
• Signs of gum disease
• Loose or damaged teeth

Professional dental cleaning under anesthesia is the only way to safely remove established tartar and clean below the gumline.
