Quick answer
Farm and spend Enamels
Use Enamels to remove the bottleneck you can actually see: Tooth upgrades for pressure, Brush upgrades when defense trails, and Capsules only when a better Tooth has enough upside.

Step by step
How to farm and spend enamels
Follow the steps in order, then use the planner when the guide asks you to choose between upgrades, Capsules, or farming.
- 1
Record your current Enamels
Start with the number shown in-game. The planner uses it to estimate whether you can afford a Tooth upgrade, Brush upgrade, or Capsule session.
- 2
Pick one target at a time
Choose the next Tooth upgrade, next Brush upgrade, Capsule opening session, or rare/secret chase. Avoid mixing all goals into one decision.
- 3
Use your real Enamels per wave
Default values are estimates. Replace them with your observed earnings after a few Bacteria waves for a better target estimate.
Tip: Auto Collect may improve comfort, but do not convert that into exact income until you measure it.
- 4
Upgrade before gambling when your Tooth is good
If your current Tooth is source-backed or already clearing waves well, upgrading it can be safer than spending the same Enamels on unknown Capsule odds.
- 5
Recheck after updates
Cavity Crushers is new and updated recently. Costs, rewards, and pass effects can move, so keep checked dates visible.
Common mistakes
Avoid these traps
Using old tracker rewards as current Enamel math
Keep code rewards separate from repeatable Enamel income unless you verified both.
Treating Auto Open as income
Auto Open affects Capsule convenience, not proven Enamel earning.
Ignoring Brush upgrades
If defense trails your Tooth level, the next Brush upgrade may improve wave readiness more than another Capsule pull.
FAQ
Guide questions
How do I get Enamels fast?
Official copy confirms Enamels, but exact income formulas are not public. Track your own per-wave income and use the planner.
Should I spend Enamels on Teeth or Brushes?
Upgrade Teeth when damage pressure is the bottleneck. Upgrade Brushes when wave survival or defense trails behind Tooth level.
Are Capsule costs verified?
Not enough for exact publishing. Keep Capsule plans editable until costs and odds are checked live.
Does Auto Collect change the Enamel plan?
It likely helps comfort and collection flow, but exact rate impact should be measured before making formula claims.
